The name Rosario in Hebrew letters is רוסריו. 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.
רוסריו
In short
Your name in Hebrew letters is רוסריו. Spanish for “rosary”, from Latin rosarium, “rose garden”. In Spain it is a woman's name; in Italy it is given to men. In Hebrew it is written by sound. Adding up the numbers of its letters gives 482 — the same as the Torah word עבדתו, “its service”. That number points to Torah page 128 of 354 — in the portion Mishpatim. What that portion is about: Laws of the servant, damages, theft and pledges; “an eye for an eye” as compensation; the sabbatical year; “we will do and we will hear”. The verse that begins with the first letter of your name and ends with the last is Exodus 23:19. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Rosario” — this exact spelling is what was calculated: רוסריו. 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 רוסריו gives 482.
482
The number 482 is the Torah word עבדתו — «its service» (Exodus 27:19).
If there be laid on him a ransom, then he shall give for the redemption of his life whatsoever is laid upon him.
This is from the portion Mishpatim. What it is about: Laws of the servant, damages, theft and pledges; “an eye for an eye” as compensation; the sabbatical year; “we will do and we will hear”.
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) — 482. A Torah word with the same number is עבדתו — “its service” (Exodus 27:19).
Reduced, each letter to one digit (mispar katan) — 23.
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 77. A Torah word with the same number is עז — “she-goat” (Genesis 15:9).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1942.
Squares of the letter values (mispar perati) — 83772.
Building: the sum grows with each letter (mispar bone’eh) — 2096.
The letters that come out are גפחגמפ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 214. A Torah word with the same number is ירד — “to go down” (Genesis 11:5).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 1184.
The number 482 appears in the classical books 1 time across 1 work. The earliest mention is מי השילוח.

The name רוסריו 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 רוסריו these are ר and ו. The Pentateuch has 6 such verses. The first of them is Exodus 23:19:
ראשית בכורי אדמתך תביא בית ה׳ אלהיך לא תבשל גדי בחלב אמו
This is from the portion Mishpatim. What it is about: Laws of the servant, damages, theft and pledges; “an eye for an eye” as compensation; the sabbatical year; “we will do and we will hear”.
Any name written in Hebrew letters is a number: רוסריו = 482. And every date has a number of its own. There is a day in the year when the two coincide.
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.
