מנסור
In short
Your name in Hebrew letters is מנסור. Mansur is a name of Arabic origin, from “mansur”, which means “victorious”. The caliph al-Mansur founded the city of Baghdad in 762. In Hebrew it is written by sound. Adding up the numbers of its letters gives 356 — the same as the Torah word פעור, “Peor, mountain in Moab”. That number points to Torah page 2 of 354 — in the portion Bereshit. What that portion is about: Creation in six days and the Sabbath; Adam and Eve in the garden; Cain and Abel; ten generations to Noah. The verse that begins with the first letter of your name and ends with the last is Genesis 19:22. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Mansur” — this exact spelling is what was calculated: מנסור. 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.

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) — 356. A Torah word with the same number is פעור — “Peor, mountain in Moab” (Numbers 23:28).
Reduced, each letter to one digit (mispar katan) — 23.
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 68. A Torah word with the same number is חלל — “to begin” (Genesis 4:26).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1411.
Squares of the letter values (mispar perati) — 47736.
Building: the sum grows with each letter (mispar bone’eh) — 792. A Torah word with the same number is תשבץ — “checkered work” (Exodus 28:4).
The letters that come out are יטחפג — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 110. A Torah word with the same number is עם — “people” (Genesis 11:6).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 828. A Torah word with the same number is צפנתפענח — “Zaphenath-paneah, Joseph's Egyptian name” (Genesis 41:45).
The number 356 appears in the classical books 6 times across 5 works. The earliest mention is שער הפסוקים (~1573).

The name מנסור 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 מנסור these are מ and ר. The Pentateuch has 3 such verses. The first of them is Genesis 19:22:
מהר המלט שמה כי לא אוכל לעשות דבר עד באך שמה על כן קרא שם העיר צוער
This is from the portion Vayera. What it is about: Three visitors at Abraham's tent; the plea for Sodom; the birth of Isaac; the binding of Isaac on Mount Moriah.
The name מנסור has no such day. The numbers of the dates in a year cover 326 values out of 940, and 356 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.
