The check digit in a UPC number is that value of d for which the following sum totals a number whose final digit is 0:
3a, +az + 3a, + a4+ 3a5 + ag+ 3a, +ag +3a, +a10 + 3a11 +d
0-44600-01628-d
In our example, 3(0) + 4 + 3(4) + 6+ 3(0) + 0+ 3(0) + 1 + 3(6) + 2 + 3(8) + d must be a sum that ends in 0.
