/*
    To calculate the RUC number for your cedula:
    Starting with the rightmost digit, multiply it by 2.
    Then, multiply the next digit by 3 and add it to the first result.
    Then, multiply the next digit by 4 and add it to the running total.
    ... keep doing this.
    Finally, take the remainder of the the total divided by 11 (called the modulo), 
    and subtract it from 11.
