CWR error: An IPI name number's own check digits say it is wrong
What it means
An IPI name number ends in two digits calculated from the nine before them, and they don't agree. The writer or publisher named here won't be matched to the right party, so their share goes unallocated.
How to fix it
Look the party up in the IPI system and copy the eleven digits exactly, leading zeros included. Songlinks (https://songlinks.io/ipi-name-number-lookup) shows which of a writer's registrations carry an IPI name number.
