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) — 1040.
Reduced, each letter to one digit (mispar katan) — 21. A Torah word with the same number is אך — “only, surely” (Genesis 7:23).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 57. A Torah word with the same number is מזבח — “altar” (Genesis 8:20).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1426.
Squares of the letter values (mispar perati) — 93452.
Building: the sum grows with each letter (mispar bone’eh) — 1694.
The letters that come out are בכקפט — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 211. A Torah word with the same number is ירא — “to fear” (Genesis 3:10).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 986.

The name שלדון 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 שלדון these are ש and נ. The Pentateuch has 4 such verses. The first of them is Genesis 42:32:
שנים עשר אנחנו אחים בני אבינו האחד איננו והקטן היום את אבינו בארץ כנען
This is from the portion Miketz. What it is about: Pharaoh's dreams of seven cows and seven ears; Joseph rules Egypt; the brothers come for grain; the cup in Benjamin's sack.
