In short
Your name in Hebrew letters is מסרוף. Adding up the numbers of its letters gives 386 — the same as the Torah word לשון, “tongue, language”. That number points to Torah page 32 of 354 — in the portion Vayera. What that portion is about: Three visitors at Abraham's tent; the plea for Sodom; the birth of Isaac; the binding of Isaac on Mount Moriah. The verse that begins with the first letter of your name and ends with the last is Exodus 15:4. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Mesrop” — this exact spelling is what was calculated: מסרוף. 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 מסרוף gives 386.

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) — 1106.
Reduced, each letter to one digit (mispar katan) — 26. A Torah word with the same number is והיה — “and it became” (Genesis 2:10).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 71. A Torah word with the same number is מלא — “to fill” (Genesis 1:22).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1621.
Squares of the letter values (mispar perati) — 51636.
Building: the sum grows with each letter (mispar bone’eh) — 1132.
The letters that come out are יחגפו — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 107. A Torah word with the same number is גלעד — “Gilead, region east of Jordan” (Genesis 31:21).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 803. A Torah word with the same number is באתת — “with the banners” (Numbers 2:2).
The number 386 appears in the classical books 15 times across 10 works. The earliest mention is ספר קרניים (~1400).

The name מסרוף 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 מסרוף these are מ and פ. The Pentateuch has exactly one such verse — Exodus 15:4:
מרכבת פרעה וחילו ירה בים ומבחר שלשיו טבעו בים סוף
This is from the portion Beshalach. What it is about: The parting of the sea and the song of Moses and Miriam; manna and quail; water from the rock; the war with Amalek.
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.
