Yes. You don't need to know the year, just the one or two-digit lot number that follows the 6 digits of the product number. They won't have included the lot numbers in the notice if they weren't made inside the suspect time frame. I'm just surprised they go back as far as 2 for all those powders.
Understand that lots can be multiple train car quantities the distributer uses as stock, sometimes lasting for years, so if a simple serial lot numbering is used, it's not surprising that some lots last for years and that over a period of decades the lot numbers are still only one or two digits.
