The name Serafin in Hebrew letters is סרפין. 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.
סרפין
In short
Your name in Hebrew letters is סרפין. The name comes from the Hebrew word “seraphim”, “the burning ones”. This is what the Tanakh calls the fiery angels in the book of Isaiah, chapter 6. This form of the name is used in Spain and Latin America. In Hebrew it is written by sound. Adding up the numbers of its letters gives 400 — the same as the Torah word שנים, “two”. That number points to Torah page 46 of 354 — in the portion Toldot. What that portion is about: The birth of Esau and Jacob; the birthright sold for lentil stew; Isaac's wells; Jacob receives the blessing. The verse that begins with the first letter of your name and ends with the last is Joshua 12:2. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Serafin” — this exact spelling is what was calculated: סרפין. 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 סרפין gives 400.
400
The number 400 is the Torah word שנים — «two» (Genesis 1:16).
and give thee the blessing of Abraham, to thee, and to thy seed with thee; that thou mayest inherit the land of thy sojournings, which G-d gave unto Abraham.'
This is from the portion Toldot. What it is about: The birth of Esau and Jacob; the birthright sold for lentil stew; Isaac's wells; Jacob receives the blessing.
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) — 1050.
Reduced, each letter to one digit (mispar katan) — 22. A Torah word with the same number is יחד — “together” (Genesis 13:6).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 76. A Torah word with the same number is עבד — “servant” (Genesis 9:25).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1705.
Squares of the letter values (mispar perati) — 52600.
Building: the sum grows with each letter (mispar bone’eh) — 1410.
The letters that come out are חגומט — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 66. A Torah word with the same number is כמו — “like, as” (Genesis 19:15).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 837. A Torah word with the same number is המשבצת — “the settings” (Exodus 28:14).
The number 400 appears in the classical books 17 times across 16 works. The earliest mention is בעל הטורים על התורה (~1300).

The name סרפין 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
The Pentateuch has no verse that begins with ס and ends with נ. The custom allows the whole Tanakh — the Prophets and the Writings have 2 such verses. The first of them is Joshua 12:2:
סיחון מלך האמרי היושב בחשבון משל מערוער אשר על שפת נחל ארנון ותוך הנחל וחצי הגלעד ועד יבק הנחל גבול בני עמון
A verse whose whole sum equals your name
לא יטמא בעל בעמיו להחלו
Leviticus 21:4 · 19 letters in the verse
All the letters of this verse add up to 400 — exactly your name's number. The Pentateuch has 5,853 verses, and only 200 of them fall below 1000. Of the 2,980 names in our index, 80 match this way — about one name in thirty-seven.
The name סרפין has no such day. The numbers of the dates in a year cover 326 values out of 940, and 400 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.
