Not a correct ISBN-13 |

The ISBN 9790072263787 begins with 979, which is reserved for future ISBN; at the time of ISBN-13 coming into force no country ranges for ISBN-13 were defined, so that (in addition to the wrong check digit) it may be doubted that this is an assigned ISBN at this time. | To the home page |
