The name Segolene in Hebrew letters is סגולן. 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.
סגולן
In short
Your name in Hebrew letters is סגולן. Ségolène is a French name of Germanic origin: sigu, “victory”, and lind, “gentle”. Saint Ségolène was an abbess near Albi in the 7th century, and the French politician Ségolène Royal carries the name. In Hebrew it is written by sound. Adding up the numbers of its letters gives 149 — the same as the Torah word קדמה, “east of”. That number points to Torah page 149 of 354 — in the portion Ki Tisa. What that portion is about: The half-shekel for the census; the golden calf and the broken tablets; the thirteen attributes of mercy; the second tablets. The verse that begins with the first letter of your name and ends with the last is Joshua 12:2. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Segolene” — this exact spelling is what was calculated: סגולן. 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.

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) — 799. A Torah word with the same number is השפחות — “the maidservants” (Genesis 33:1).
Reduced, each letter to one digit (mispar katan) — 23.
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 50. A Torah word with the same number is כל — “all, every” (Genesis 1:21).
Cumulative: a letter plus all letters before it (mispar kidmi) — 582. A Torah word with the same number is למצותיו — “to his commandments” (Exodus 15:26).
Squares of the letter values (mispar perati) — 7045.
Building: the sum grows with each letter (mispar bone’eh) — 440. A Torah word with the same number is שמנים — “eighty” (Genesis 5:25).
The letters that come out are חרפכט — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 317. A Torah word with the same number is שחט — “to slaughter” (Genesis 22:10).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 395. A Torah word with the same number is מנשה — “Manasseh, son of Joseph” (Genesis 41:51).
The number 149 appears in the classical books 6 times across 6 works. The earliest mention is בעל הטורים על התורה (~1300).

The name סגולן 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
The Pentateuch has no verse that begins with ס and ends with נ. The custom allows the whole Tanakh — the Prophets and the Writings have 2 such verses. The first of them is Joshua 12:2:
סיחון מלך האמרי היושב בחשבון משל מערוער אשר על שפת נחל ארנון ותוך הנחל וחצי הגלעד ועד יבק הנחל גבול בני עמון
«And it came to pass on the morrow, that Moses said unto the people: 'Ye have sinned a great sin; and now I will go up unto HaShem, peradventure I shall make atonement for your sin.'»
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.
