Trying to identify Vishay SMD from markings on reel

I want to try to sell a factory sealed reel of SMD resistors, so don't want to break the factory seal to read the actual value unless I have to. The reel is marked 'Vishay CRCW2512 68 1% R67', my quandary is that right below this first line, it reads:
'CPN: CRCW2512680J'
I'm thinking the 'CPN' might mean 'Customer Part Number', and that I should ignore it(?)
The first line seems obvious: Series CRCW Case Size 2512 68 Ohms 1% Tolerance (I don't know what the 'R67' is for)
I've spent an hour trying to find the old CRCW data sheet, and can only find presently available part numbers.
Previously, a Dale SMD would read '680' for 68 Ohms, and 681 for 680 Ohms.
As near as I can tell from my Google search, NOW, Vishay marks a 680 Ohm SMD AS 680 (instead of previous 681)
And the 'J' suffix on the 'CPN' second line would indicate a 5% Tolerance for presently available Vishay SMD resistors.
What do you think? Just completely disregard the 'CPN' line, and assume this is a reel of 68 Ohm resistors at 1% Tolerance?
Thanks for any guesses.

Hello,

The R67 has to do with the packaging.
Have a look at page 3 of the attached PDF:
Vishay_CRCW_resistors_partnumber.png
This table has a "translation" to the new numbers.

Bertus,
Thanks for all the research on this.
The part number in your first post is the second line on the reel identification sticker.
I just can't figure-out why the first line reads CRCW2512 68 1% R67.
The sticker IS stamped 'VISHAY', so it has to be the original marking from the factory.
I can only assume there was some kind of labeling error at the factory print-out for the sticker.
(And that this happened when the Dale switch-over to Vishay took place.
... Looks like to me I'm going to break the factory seal to solve this mystery.
Thanks again for the time you took to check on this.
