[mariagould]

doi:10.18737 and doi:10.17602 are Crossref prefixes that are configured as DataCite prefixes in EZID.

2 DOIs registered on 10.18737: doi:10.18737/D7PP4Q - example DOI that can be deleted (deleted Jan 6 2022) doi:10.18737/D7K01R - example DOI that can be deleted (deleted Jan 6 2022)

2 DOIs registered on 10.17602: doi:10.17602/C2QP4Z - example DOI that can be deleted (deleted Jan 6 2022) doi:10.17602/C2F596 - erroneous DOI (created before we learned about the registration agency problem) that should be deleted (deleted Jan 6 2022)

To do:

• [x] Determine if doi:10.18737/D7PP4Q can be deleted

• [x] Delete DOIs

• [x] Deactivate shoulders
