 *    The final digit of a Universal Product Code is a check digit computed as follows:
 *
 *       1) Take digits up to but not including the check digit.
 *       2) Sum the digits in the odd-numbered positions (first, third, fifth, etc.) together and multiply by three.
 *       3) Add the sum of digits in the even-numbered positions (0th, 2nd, 4th, 6th, etc.) to the result.
 *       4) Take result modulo 10
