Which spelling details matter here?
Compound numbers from 21 through 99 join the tens word and the ones word with a hyphen. In 6,651, the 51 part combines fifty and one, producing fifty-one. Hundreds are written by placing a digit word before hundred. In 6,651, the hundreds part is six hundred. American English usually omits and after hundred when more digits follow. That is why this page writes six thousand six hundred fifty-one without adding and before the final part. English reads large numbers in three-digit groups. 6,651 reaches the thousand group, so the group six is followed by the scale name thousand. Scale names stay singular inside exact number names. English writes six thousand without adding a plural s to the scale name.
