ארתחשסתא
In short
Your name in Hebrew letters is ארתחשסתא. A Tanakh name: a title of several Persian kings (first in Ezra 4:7; 17 mentions in the Tanakh). Adding up the numbers of its letters gives 1370. That number points to Torah page 308 of 354 — in the portion Eikev. What that portion is about: “Because you will heed”: the land of seven fruits; the blessing after meals; manna as a test; the second paragraph of the Shema. The verse that begins with the first letter of your name and ends with the last is Genesis 24:45. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Artaxerxes” — this exact spelling is what was calculated: ארתחשסתא. 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.

The verse this place falls on is Devarim (Deuteronomy) 8:3:
וַיְעַנְּךָ וַיַּרְעִבֶךָ וַיַּאֲכִלְךָ אֶת הַמָּן אֲשֶׁר לֹא־יָדַעְתָּ וְלֹא יָדְעוּן אֲבֹתֶיךָ לְמַעַן הוֹדִעֲךָ כִּי לֹא עַל־הַלֶּחֶם לְבַדּוֹ יִחְיֶה הָאָדָם כִּי עַל־כָּל־מוֹצָא פִי־ה׳ יִחְיֶה הָאָדָם
And He afflicted thee, and suffered thee to hunger, and fed thee with manna, which thou knewest not, neither did thy fathers know; that He might make thee know that man doth not live by bread only, but by every thing that proceedeth out of the mouth of HaShem doth man live.
This is from the portion Eikev. What it is about: “Because you will heed”: the land of seven fruits; the blessing after meals; manna as a test; the second paragraph of the Shema.
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) — 1370.
Reduced, each letter to one digit (mispar katan) — 29. A Torah word with the same number is דכה — “crushed” (Deuteronomy 23:2).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 110. A Torah word with the same number is עם — “people” (Genesis 11:6).
Cumulative: a letter plus all letters before it (mispar kidmi) — 5173.
Squares of the letter values (mispar perati) — 453666.
Building: the sum grows with each letter (mispar bone’eh) — 6029.
The letters that come out are תגאסבחאת — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 875.
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 2442.
The name ארתחשסתא 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 ארתחשסתא these are א and א. The Pentateuch has 8 such verses. The first of them is Genesis 24:45:
אני טרם אכלה לדבר אל לבי והנה רבקה יצאת וכדה על שכמה ותרד העינה ותשאב ואמר אליה השקיני נא
This is from the portion Chayei Sarah. What it is about: Sarah's death and the purchase of the cave of Machpelah; the servant seeks a wife for Isaac; Rebecca at the well; Abraham's death.
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.
