Small note though, the right most digit is always considered an odd digit in a UPC Code. Your function works because you you only allow UPC-A codes to be inputted for the CalculateCheckDigit function. Removing the length check and starting from the right ( with the right most digit being odd ), would allow you to calculate the check digit for EAN, UPCA, and GSI.. Just a thought. Good article.
