Formula needed to extract numbers from the right, varying lengths

[Caleigh]

Hi Everyone, I've searched for different versions of a formula that can assist with this, but cannot seem to find anything that will work.
I have varying lengths of numbers in a column, and I need to move them to a new column in a specific format. The problem I'm running into is because the lengths of the data will change, so the only format I can rely on is if I begin the extraction from the right and not the left.

The last 7 numbers will be consistent with what I need (and then the first number should be whatever is leftover) but since the lengths of the original numbers can change (there can be as many as 12 or 15), I'm not having any luck with a MID formula. Flash fill works, but only after entering a few manually, and I'm trying to automate this as much as possible.

I appreciate any help with a formula that will pull from the right instead of the left, because I'm at a loss.

thank you,
