| This might be a well-formed ISBN-13, but its check-digit is missing. The correct check digit would be: 9. | |||||||||
| Hyphenation provided ("978-600-182-40-2") is implausible so ignored it. | |||||||||
| Correcting check-digit gives: 978-600-182-402-9 which appears to be valid. The governing agency is: Iran. | |||||||||
