What is Validating Universal Product Codes about?
The document discusses Universal Product Code (UPC) validation through checksum calculation. It provides examples of both valid and invalid UPC codes. The checksum is calculated by multiplying each UPC digit by its place value and summing the results. If the total is divisible by 10, the code is valid. For the sample product code 5-02003-91562, the checksum calculation determines the check digit should be 1, making the full valid UPC code 5-02003-91562-1.
