Conundrum: Alphagram

What number, when written as a word in English, has all of its letters in alphabetical order?

For example, “six” doesn’t work, because the letter S comes before the letter I in the word, but S comes after I in the alphabet.

The word “begin” has all five of its letters in alphabetical order, but, of course, it is not a number.

Can you find the only number that meets this requirement?

UPDATE: Number identified by Jeff. See comments for answer.
