in isbn -13 step 5 its a little bit different in book, after adding the even and odd numbers we divide it by 10 and if the remainder is 0 then we use that value otherwise we subtract the remainder from 10 to find the check digit.
Yes, I believe so... 2.2 Methods of Error Detection - Describe how a check digit is used to detect errors in data entry and identify examples of when a check digit is used, including international standard book numbers (ISBN) and bar codes.
Modulo 11: A check digit according to Modulo 11 is used for ISBN. First all digits are multiplied individually with a multiplier. The multiplier corresponds to the position of the digit + 1. All resulting products are added. The result is then divided by 11. The resulting remainder is the check digit. If the check digit is 10, this number shall not be used as ISBN. The code would therefore be invalid.

Modulo 11: A check digit according to Modulo 11 is used for ISBN.
First all digits are multiplied individually with a multiplier. The multiplier corresponds to the position of the digit + 1. All resulting products are added. The result is then divided by 11. The resulting remainder is the check digit. If the check digit is 10, this number shall not be used as ISBN. The code would therefore be invalid.
