The name Sethur in Hebrew letters is סתור. 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.
סתור
In short
Your name in Hebrew letters is סתור. A Tanakh name: the name of an Israelite (first in Numbers 13:13; 1 mention in the Tanakh). Meaning, per Strong’s dictionary (1890): “hidden”. Adding up the numbers of its letters gives 666 — the same as the Torah word סתור, “Sethur, spy from Asher”. That number points to Torah page 312 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 Psalms 111:8. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Sethur” — this exact spelling is what was calculated: סתור. 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 סתור gives 666.
666
The number 666 is the Torah word סתור — «Sethur, spy from Asher» (Numbers 13:13).
Wherefore Levi hath no portion nor inheritance with his brethren; HaShem is his inheritance, according as HaShem thy G-d spoke unto him.--
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) — 666. A Torah word with the same number is סתור — “Sethur, spy from Asher” (Numbers 13:13).
Reduced, each letter to one digit (mispar katan) — 18. A Torah word with the same number is חי — “living” (Genesis 1:20).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 63. A Torah word with the same number is חנה — “to encamp” (Genesis 26:17).
Cumulative: a letter plus all letters before it (mispar kidmi) — 2566.
Squares of the letter values (mispar perati) — 203636.
Building: the sum grows with each letter (mispar bone’eh) — 1652.
The letters that come out are חאפג — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 92. A Torah word with the same number is מאומה — “anything” (Genesis 22:12).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 1048. A Torah word with the same number is מחתרת — “breaking in” (Exodus 22:1).
The number 666 appears in the classical books 3 times across 3 works. The earliest mention is לשון חכמים (~1900).

The verse of your name
The Pentateuch has no verse that begins with ס and ends with ר. The custom allows the whole Tanakh — the Prophets and the Writings have 2 such verses. The first of them is Psalms 111:8:
סמוכים לעד לעולם עשוים באמת וישר
A verse whose whole sum equals your name
ועל צבא מטה בני גד אליסף בן דעואל
Numbers 10:20 · 26 letters in the verse
All the letters of this verse add up to 666 — exactly your name's number. The Pentateuch has 5,853 verses, and only 200 of them fall below 1000. Of the 2,980 names in our index, 80 match this way — about one name in thirty-seven.
The name סתור has no such day. The numbers of the dates in a year cover 326 values out of 940, and 666 is not among them. Half of all names are like this — neither good nor bad, just a fact of counting.

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.
