For example:
ISBN 0 2 0 1 1 8 3 9 9 4
Multiplier 10 9 8 7 6 5 4 3 2 1
Product 0 18 0 7 6 40 12 27 18 4
Product add 0 + 18 + 0 + 7 + 6 + 40 + 12 + 27 + 18 + 4 = 132
ISBN uses Modulus 11 for the check digit. In this case, 132 is divisible by 11, so it passes the check digit.
To set the check digit multiplier, scan the following barcode, and then scan numbers and letters to form the
multiplier string from Alphanumeric Barcodes. Then scan End of Message on page 319.
