cw racing z2000 serial number?

[Gish]

looking at buying a 86  cw racing z2000 frame & forks from usa. theres pictures of the bike but none of the serial number so i sent the seller an email asking for the serial number and this is what he sent me back;

PO868775  DS50721782  and said it was under cranckcase.
could anyone who has owned a cw tell me whats all the numbers for and should it have two sets of numbers.

any info would be most helpful
