Serial number breakdown

[matdavid]

I need to create a regular expression to find the serial numbers of UCS blades and chassis.  I know the middle 4 digits indicate the year and month of manufacture.  The questtion comes with the first 3 and the last 4 characters.  I know they can be a mix of numbers and letters, but I'd like the pattern to be as specific as possible.

Example SN: JAE2445044T

JAE is the code for the manufacturing location

24 is the year code (subtract 4 from this value, meaning it was manufactured in 2020)

45 is the week code (meaning it was manufactured in the 45th week of the calendar year, which would be early November)

The final 4 digits are the part ID. These are unique values assigned to each device produced in that facility in that week of that year.
