Wrong ISBN No

[Yiota]

I am trying to register another book titled "Η ουσία της Ζωής" by Τάκης Μιχαηλίδης with the following ISBN 978-618-5166-56-4 but the above mentioned book has already been registered with the same ISBN.
How can i ask the auther to check it again?
On my behalf i am sure this is the ISBN number. I can always sent a photo of it.

Thank you!
I guess I shouldn't have registered the book before I check for your answer. Which was really imediate, unlike i had imagined. Sorry!
At this point I cant make any changes, can't I?
