Extra numbers inside

[Trifcho]

Hi all,
Except the engraved key numbers inside of my Isis, on the washer that hold the button's spring, there are engraved extra seven numbers. Any ideas for what are they? Thanks

The numbers on the washer are for the disc game, but in case i just like the physical puzzles i don't know more about this online game. The other numbers are the numbers you need to proof that you solved it when you have registered your isis on the isis adventure website.
