Substitute each of the capital letters in bold by a different digit from 0 to 9 to satisfy this alphametic equation. Neither A nor C is zero and S ≥ 2.

C
∫ x^-S dx = .COLORS
A

(In reply to re: computer solution by Harry)

Oh, my! I did assume what amounted to S was 5. Actually, I mistook the one in the exponent for an actual 5. I should have pressed ctrl-+ a few times to enlarge the font and see that the exponent was -S rather than -5. Wow!
