Hello hdodo2003,
I usually do not deal with part number and such. This is because if it's a counterfeit disk, the disk can have any number the counterfeiter wants to put on it.
If you are receiving a Non-genuine message from your software and you would like me to look into it, download and run the Genuine Diagnostics tool (MGADiag.exe) at this link

Thank you,
