The name Arsenio in Hebrew letters is ארסניו. 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.
ארסניו
In short
Your name in Hebrew letters is ארסניו. This name comes from the Greek language: the word arsen means “male, manly”. Arsenio Rodríguez was a famous Cuban musician of the 20th century. In Hebrew it is written by sound. Adding up the numbers of its letters gives 327 — the same as the Torah word שכבה, “layer of dew”. That number points to Torah page 327 of 354 — in the portion Shoftim. What that portion is about: Judges and officers; “justice, justice shall you pursue”; the king and his scroll; cities of refuge; witnesses; laws of war. The verse that begins with the first letter of your name and ends with the last is Genesis 9:4. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Arsenio” — this exact spelling is what was calculated: ארסניו. 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 ארסניו gives 327.
327
The number 327 is the Torah word שכבה — «layer of dew» (Exodus 16:13).
And if HaShem thy G-d enlarge thy border, as He hath sworn unto thy fathers, and give thee all the land which He promised to give unto thy fathers--
This is from the portion Shoftim. What it is about: Judges and officers; “justice, justice shall you pursue”; the king and his scroll; cities of refuge; witnesses; laws of war.
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) — 327. A Torah word with the same number is שכבה — “layer of dew” (Exodus 16:13).
Reduced, each letter to one digit (mispar katan) — 21. A Torah word with the same number is אך — “only, surely” (Genesis 7:23).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 66. A Torah word with the same number is כמו — “like, as” (Genesis 19:15).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1322.
Squares of the letter values (mispar perati) — 46237.
Building: the sum grows with each letter (mispar bone’eh) — 1422.
The letters that come out are תגחטמפ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 540. A Torah word with the same number is שמר — “to keep, guard” (Genesis 2:15).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 879.
The number 327 appears in the classical books 1 time across 1 work. The earliest mention is רפואה למכה (~1780?).

The name ארסניו 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 ארסניו these are א and ו. The Pentateuch has 55 such verses. The first of them is Genesis 9:4:
אך בשר בנפשו דמו לא תאכלו
This is from the portion Noach. What it is about: The flood and the ark; the rainbow as a sign of the covenant; the tower of Babel; ten generations from Noah to Abraham.
Any name written in Hebrew letters is a number: ארסניו = 327. And every date has a number of its own. There is a day in the year when the two coincide.
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.
