The name Arsen in Hebrew letters is ארסן. Below: how its number adds up, which page of the Torah it falls on and what verse stands there. Everything is computed, nothing is guessed.
ארסן
In short
Your name in Hebrew letters is ארסן. This name comes from the Greek language: the word arsen means “male, manly”. Saint Arsenius the Great lived in Egypt in the 4th and 5th centuries; the name is common in Armenia. In Hebrew it is written by sound. Adding up the numbers of its letters gives 311 — the same as the Torah word איש, “man”. That number points to Torah page 311 of 354 — in the portion Eikev. What that portion is about: “Because you will heed”: the land of seven fruits; the blessing after meals; manna as a test; the second paragraph of the Shema. The verse that begins with the first letter of your name and ends with the last is Genesis 36:27. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Arsen” — this exact spelling is what was calculated: ארסן. A name from the Tanakh — its Tanakh spelling is used. If your name is spelled differently, correct the Hebrew spelling and the report is recomputed.
Adding up the letters of the name ארסן gives 311.
311
The number 311 is the Torah word איש — «man» (Genesis 2:23).
And when HaShem sent you from Kadesh-barnea, saying: 'Go up and possess the land which I have given you'; then ye rebelled against the commandment of HaShem your G-d, and ye believed Him not, nor hearkened to His voice.
This is from the portion Eikev. What it is about: “Because you will heed”: the land of seven fruits; the blessing after meals; manna as a test; the second paragraph of the Shema.
The same number, 311, is given by these Tanakh names:

Other ways of counting
The tradition counts the same name in several ways. The main one is above: each letter is its number. The other eight are old and checkable too; each gives its own number, and many of them have a Torah word with the same number.
Final letters as 500–900 (mispar gadol) — 961.
Reduced, each letter to one digit (mispar katan) — 14. A Torah word with the same number is יד — “hand” (Genesis 3:22).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 50. A Torah word with the same number is כל — “all, every” (Genesis 1:21).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1246.
Squares of the letter values (mispar perati) — 46101.
Building: the sum grows with each letter (mispar bone’eh) — 774. A Torah word with the same number is בשבעת — “with the oath of” (Numbers 5:21).
The letters that come out are תגחט — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 420. A Torah word with the same number is ענש — “to fine, punish” (Exodus 21:22).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 847.
The number 311 appears in the classical books 16 times across 11 works. The earliest mention is ספר קרניים (~1400).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 311. The channel posts one number a day, one verse and the Torah page it lands on. Nothing after it, no mailing list.

For an engraving, a sign or a tattoo, show the spelling to someone who reads Hebrew: transliterating a name is a choice, not the only option.
The name ארסן does not stand as a word in the Pentateuch — as with most names, including many Tanakh names from the later books.
The verse of your name
There is a custom: at the end of the prayer one says a Torah verse that begins with the first letter of one's name and ends with its last. For ארסן these are א and נ. The Pentateuch has 35 such verses. The first of them is Genesis 36:27:
אלה בני אצר בלהן וזעון ועקן
This is from the portion Vayishlach. What it is about: Wrestling with the angel and the name Israel; the meeting with Esau; Dinah in Shechem; the birth of Benjamin and Rachel's death.
The name ארסן has no such day. The numbers of the dates in a year cover 326 values out of 940, and 311 is not among them. Half of all names are like this — neither good nor bad, just a fact of counting.
Add a date of birth and the verse of meeting from that week's portion is added to the reading.
Each Hebrew letter has a number; a word's number is their sum (alef 1 … tav 400). The page is the remainder modulo 354: the Torah divided into 354 pages of 861 letters, as the lunar year has 354 days. Everything can be checked by hand.
