ISBN Formula
ISBN-10: Checksum calculated using modulo 11 (digits 1-9 multiplied by position number).
ISBN-13: Checksum calculated using modulo 10 with alternating 1 and 3 multipliers.
What's the difference between ISBN-10 and ISBN-13?
ISBN-10 uses 10 digits with modulo 11 checksum, while ISBN-13 uses 13 digits with EAN-13 format and modulo 10 checksum. ISBN-13 was introduced in 2007 to increase global availability of ISBN numbers.
Can I validate ISBNs with this tool?
Yes, the tool automatically validates ISBN numbers using standard checksum calculations before generating barcodes. Invalid ISBNs will trigger an error message.
