Since BC Math doesn't work with arbitrary base numbers, you could try using GMP functions if you have them available.

Otherwise you'll probably have to rewrite your algorithm and write your own arbitrary precision arithemtic implementation of the validation algorithm.

Use a math library like BC Math for big numbers :)
