    Did you forget how the decimal system works?

    Each place is a power of 10, simply multiply each element by 10 to its respective place. So,

    Code:
    {4,2,4,5,6,1,2} = (10^6 * 4) + (10^5 * 2) + (10^4 * 4) + (10^3 * 5) + (10^2 * 6) + (10^1 * 1) + (10^0 * 2)
    Or put all the numbers in a string, and parse it out.
