The name Datan in Hebrew letters is דתן. 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.
דתן
In short
Your name in Hebrew letters is דתן. A Tanakh name: the name of an Israelite (first in Numbers 16:1; 10 mentions in the Tanakh). Adding up the numbers of its letters gives 454 — the same as the Torah word תמיד, “continually, perpetual”. That number points to Torah page 100 of 354 — in the portion Vaera. What that portion is about: “And I appeared”: the promise of redemption in four expressions; the first seven plagues, from blood to hail. The verse that begins with the first letter of your name and ends with the last is Leviticus 23:10. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Datan” — this exact spelling is what was calculated: דתן. 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 דתן gives 454.
454
The number 454 is the Torah word תמיד — «continually, perpetual» (Exodus 25:30).
And I will bring you in unto the land, concerning which I lifted up My hand to give it to Abraham, to Isaac, and to Jacob; and I will give it you for a heritage: I am HaShem.'
This is from the portion Vaera. What it is about: “And I appeared”: the promise of redemption in four expressions; the first seven plagues, from blood to hail.
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) — 1104.
Reduced, each letter to one digit (mispar katan) — 13. A Torah word with the same number is אחד — “one” (Genesis 1:5).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 40. A Torah word with the same number is חלב — “fat” (Genesis 4:4).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1700.
Squares of the letter values (mispar perati) — 162516.
Building: the sum grows with each letter (mispar bone’eh) — 862. A Torah word with the same number is תבנית — “pattern, form” (Exodus 25:9).
The letters that come out are קאט — 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) — 946.
The number 454 appears in the classical books 13 times across 8 works. The earliest mention is מדרש לפירושים (~1450?).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 454. The channel posts one number a day, one verse and the Torah page it lands on. Nothing after it, no mailing list.
Hebrew is written from right to left. דתן has 3 letters: ד Dalet, ת Tav, ן final Nun. The first letter is Dalet, the last is final Nun.
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 דתן appears in the Torah as a word 4 times. The first time is Genesis 37:17. Another 6 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 דתן these are ד and נ. The Pentateuch has 3 such verses. The first of them is Leviticus 23:10:
דבר אל בני ישראל ואמרת אלהם כי תבאו אל הארץ אשר אני נתן לכם וקצרתם את קצירה והבאתם את עמר ראשית קצירכם אל הכהן
This is from the portion Emor. What it is about: Laws of the priests; animals without blemish; the calendar of festivals — from the Sabbath to Sukkot; the lamp and the showbread.
«And I will bring you in unto the land, concerning which I lifted up My hand to give it to Abraham, to Isaac, and to Jacob; and I will give it you for a heritage: I am HaShem.'»
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.
