Bad ISBN on a Unique Edition

[JG (Introverted Reader)]

This edition of The Girl Who Played With Fire is the only one in the database in Romanian. When I try to convert the ISBN to get the 10-digit one, I keep getting an "Invalid ISBN" message. I've tried on several different converters. I've googled the book and the first five or so pages all show the same ISBN. What should we do? Leave the ISBN that seems to be wrong? Leave it blank?

Well, it's not the check digit that's the problem.

EVERY site I can find that lists that edition with an ISBN has that one. :P I think we're stuck with it.

I've actually had books in my hand where the printed ISBN wouldn't convert to an ISBN-13. Never been sure what the problem was, but sometimes that's all you can go with.
