The final digit of an ISBN is the "check digit", and is calculated based on a weighted sum of the previous digits. Therefore, it is usually not the same for the ISBN10 and ISBN13.

You can always use an ISBN converter (like this one) to check.


ChitHwe | 15 comments OK. Because the ISBN above & below the barcode are all 13-digits, I didn't know they might not be similar.

Thanks.


ChitHwe | 15 comments Please ignore / delete this thread then. Thanks.

The 13-digit ISBNs should be the same, but you quoted the 10-digit ISBN in #1 (ISBN 9866675475).
