All 13 digit EANs with the 979 prefix are validating as ISBNs (ISBNValidator).
There are 2 issues with this.
# 979-0 prefixed numbers are allocated to the ISMN agency and represent music
works. [https://www.ismn-international.org/whatis.html]
# 979-[2-9] are unassigned at present, that is they have not yet been
allocated to a country agency (or another authority).
see attached xml (from
[www.isbn-international.org/export_rangemessage.xml|http://www.isbn-international.org/export_rangemessage.xml]
[^RangeMessage.xml] ) for the current valid ranges for ISBN
and
[https://en.wikipedia.org/wiki/List_of_ISBN_identifier_groups#Identifiers_of_the_979-_prefix]
An example unassigned 'ISBN' is 9792222222223
