I was going through my Calibre Library trying to make sure all the isbn's and other identifiers were correct (I am trying to import into Library Thing and StoryGraph) so I have each identifier in it's own column for easy reading. My question is what is this one type of identifier, I call it the mobi-asin 7 identifier and I see it only on books that I sent to amazon.

I have a lot of send to kindle books, but their identifiers are different. Although, they may also have that one above. I have sent and deleted and resent the same book many times, and each time it gets a different identifier.

Is this an older send to kindle identifier?

Any insight would be helpful.
