Is it possible? Give an example or prove impossible.
The rules.
1) You can only use each digit ONCE
2) EVERY digit (except 0) must be used.
3) You can concatenate digits to make multi-digit numbers.
4) Only the operations of addition and multiplication are allowed.
(I.E: 2 and 3 can be turned into 23 or 32 or 2+3 or 2×3)

@Ben: Ben is incorrect that makes ninety 9! (a million+2+3+4) x 5 (10 x 5) + 6 x 7 50 + 40 two + 8 = one hundred!!! yet too undesirable there's a 9 left... i'm attempting back. 2x3x4 = 24 5x6 = 30 24 + 30 = fifty 4 7x8 = fifty six fifty six - 9 = 40 5 fifty 4 + 40 5 = ninety 9 a million + ninety 9 = one hundred So I end: a million + 2 x 3 x 4 + 5 x 6 + 7 x 8 -9 Wow. I had some hardship on that.

I know a few tricks...
(9)(8) + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 100
(1)(3)(8) + (7)(4) + (6)(5) + (9)(2) = 100
1 + 2 + 3 + 4 + 5 + 6 + 7 + (8)(9) =100
