Largest product in a series

Write a program that, when given a string of digits, can calculate the largest product for a series of consecutive digits of length n.

For example, for the input '0123456789', the largest product for a series of 3 digits is 504 (7 * 8 * 9), and the largest product for a series of 5 digits is 15120 (5 * 6 * 7 * 8 * 9).

For the input '73167176531330624919225119674426574742355349194934', the largest product is 23520 (pretty sure this is for 6 consecutive numbers).
