Proofread, interconvert, validate and tidy ISBN-10 and ISBN-13 references. CMP ISBN Validator will help you interconvert, tidy up, and validate ISBN-10 and ISBN-13s (International Standard Book Numbers). It tidies them into standard form with the dashes in the correct places (the rules where they go are quite complicated). It also validates the group number and the check digit. Just paste the raw ISBN-10 or ISBN-13 into the top raw box, click Tidy then copy the tidied ISBN-10 or ISBN-13 from the bottom boxes. A tidied ISBN looks like this: 0-9600688-8-0 or 0-13-625666-X or 978-0-00-000000-2.

This Java Applet (that can also be run as an application) needs 32-bit (not 64-bit) Java 1.5 or later.

13-digit ISBN numbers
This program also handles the new Bookland EAN-13, 13-digit, bar-code ISBNs. It handles both 10-digit and 13-digit ISBNs. T All it does is prepend 978- to the old number and recompute the check digit, e. g.
0-915972-22-0 becomes 978-0-915972-22-7.
0-13-625666-X becomes 978-0-13-625666-3.
This program displays both the ISBN-10 and ISBN-13, with dashes in the right place, given either, The new Bookland EAN-13 check digit is computed in an unusual way with mod 10 and weight 3. This means the 13-digit ISBN numbers are always purely numeric. There is never an X check digit as there is sometimes with the mod-10, 10-digit ISBNs. 10-digit ISBNs and 12-digit UPCs are being unified as 13-digit EANs.
