That number points to Torah page 91 of 354 — in the portion Vayechi. What that portion is about: Jacob blesses Ephraim and Manasseh and all his sons; Jacob's death and burial in Hebron; Joseph's death. The verse that begins with the first letter of your name and ends with the last is Genesis 15:19. Each of these steps is laid out below with its sources. Every figure can be checked by hand.

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) — 91. A Torah word with the same number is מלאך — “messenger, angel” (Genesis 16:7).
Reduced, each letter to one digit (mispar katan) — 10. A Torah word with the same number is בדד — “alone” (Numbers 23:9).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 28. A Torah word with the same number is כח — “strength” (Genesis 4:12).
Cumulative: a letter plus all letters before it (mispar kidmi) — 461. A Torah word with the same number is איתן — “firm, enduring” (Genesis 49:24).
Squares of the letter values (mispar perati) — 6501.
Building: the sum grows with each letter (mispar bone’eh) — 173. A Torah word with the same number is ספיחיה — “its aftergrowth” (Leviticus 25:11).
The letters that come out are תומ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 446.
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 212. A Torah word with the same number is ריב — “quarrel, dispute” (Genesis 26:20).
The number 91 appears in the classical books 67 times across 32 works. The earliest mention is בעל הטורים על התורה (~1300).

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 אפי these are א and י. The Pentateuch has 17 such verses. The first of them is Genesis 15:19:
את הקיני ואת הקנזי ואת הקדמני
This is from the portion Lech Lecha. What it is about: “Go forth”: Abraham leaves Haran; the promise of land and offspring; the covenant between the pieces; circumcision.
