Thank you for you help

I came across an issue after reviewing the data

The core number is the 12345 portion, as assumed. However, there are some filenames that have multiple underscore characters in the name, before it gets to the version value.

Examples:

g05495_1_-v1.pdf
21586_rework_bore_tool_-v2.pdf
4148-t-14119_-v1.pdf
zprt0019548_wiper_die-nc_-1.pdf
zprt0016809_fg_tooling_A2.pdf

The -v1, -v2, -v1, -1, A2 are the version keys, and everything before that is the core document number. Any thoughts on how to address these?
