Pattern for CURIES

Compact URIs (CURIEs) constructed from Enzyme Commission Code should match this regular expression:

Example CURIEs
2000 The ENZYME database in 2000
GitHub Issue
Metaregistry Enzyme Commission Code

The metaregistry provides mappings between the Bioregistry and other registries. There are 11 mappings to external registries for this resource with 9 unique external prefixes.
