The name Jaasu in Hebrew letters is יעשו. 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.
יעשו
In short
Your name in Hebrew letters is יעשו. A Tanakh name: the name of an Israelite (first in Ezra 10:37; 2 mentions in the Tanakh). Meaning, per Strong’s dictionary (1890): “they will do”. 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 Genesis 9:27. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Jaasu” — this exact spelling is what was calculated: יעשו. 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 יעשו 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) — 386. A Torah word with the same number is לשון — “tongue, language” (Genesis 10:5).
Reduced, each letter to one digit (mispar katan) — 17. A Torah word with the same number is טוב — “good” (Genesis 1:4).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 53. A Torah word with the same number is אבן — “stone” (Genesis 2:12).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1496.
Squares of the letter values (mispar perati) — 95036.
Building: the sum grows with each letter (mispar bone’eh) — 856. A Torah word with the same number is תתנו — “you shall give” (Genesis 34:9).
The letters that come out are מזבפ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 129. A Torah word with the same number is נטע — “to plant” (Genesis 2:8).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 522. A Torah word with the same number is בנתיכם — “your daughters” (Genesis 34:9).
The number 386 appears in the classical books 15 times across 10 works. The earliest mention is ספר קרניים (~1400).

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 יעשו appears in the Torah as a word 10 times. The first time is Genesis 3:7. Another 39 times it stands with prefixes — “and”, “in”, “the”.
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 יעשו these are י and ו. The Pentateuch has 7 such verses. The first of them is Genesis 9:27:
יפת אלהים ליפת וישכן באהלי שם ויהי כנען עבד למו
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.
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.
