The name Arthur in Hebrew letters is ארתור. 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.
ארתור
In short
Your name in Hebrew letters is ארתור. Origin uncertain; often linked to Celtic artos, “bear”, or to the Roman name Artorius. It is known from the legends of King Arthur. In Hebrew it is written by sound. Adding up the numbers of its letters gives 807 — the same as the Torah word תאות, “utmost bound of”. That number points to Torah page 99 of 354 — in the portion Shemot. What that portion is about: Slavery in Egypt; Moses in the basket on the Nile; the burning bush and the Name; the first audience with Pharaoh. The verse that begins with the first letter of your name and ends with the last is Genesis 23:15. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Arthur” — this exact spelling is what was calculated: ארתור. 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 ארתור gives 807.
807
The number 807 is the Torah word תאות — «utmost bound of» (Genesis 49:26).
There is no straw given unto thy servants, and they say to us: Make brick; and, behold, thy servants are beaten, but the fault is in thine own people.'
This is from the portion Shemot. What it is about: Slavery in Egypt; Moses in the basket on the Nile; the burning bush and the Name; the first audience with Pharaoh.
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) — 807. A Torah word with the same number is תאות — “utmost bound of” (Genesis 49:26).
Reduced, each letter to one digit (mispar katan) — 15. A Torah word with the same number is זוב — “to flow” (Exodus 3:8).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 69. A Torah word with the same number is אביון — “poor, needy” (Exodus 23:6).
Cumulative: a letter plus all letters before it (mispar kidmi) — 3107.
Squares of the letter values (mispar perati) — 240037.
Building: the sum grows with each letter (mispar bone’eh) — 2217.
The letters that come out are תגאפג — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 487. A Torah word with the same number is זפת — “pitch” (Exodus 2:3).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 1549.
The number 807 appears in the classical books 2 times across 2 works. The earliest mention is מועד לכל חי (~1861).

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 ארתור 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 ארתור these are א and ר. The Pentateuch has 15 such verses. The first of them is Genesis 23:15:
אדני שמעני ארץ ארבע מאת שקל כסף ביני ובינך מה הוא ואת מתך קבר
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.

The name ארתור has no such day. The numbers of the dates in a year cover 326 values out of 940, and 807 is not among them. Half of all names are like this — neither good nor bad, just a fact of counting.
