Can you take the PC-40 to your LBS for a match up? The SRAM chains
I've used are PC-8xx (830, 850, etc) for derailer bikes. This is for
7 & 8 speeds. My IGH hub bike uses PC-1, slightly wider. If it's for
a Rohloff set-up, you're probably looking for the wider stuff like
PC-1.

Yes, they did change the numbering scheme. I used to the x59 or x69. I’ve bought an 870 for my old cannondale hoping that it’s equivalent. You can look at their suite of chains at http://www.sram.com/sram/road/category/45. But note that although an 870 is in an 8 speed category and 971 is in the 9 speed category (seems to make sense), they both claim compatibility with both 8 & 9 speed drivetrains.
However on page 70 of technical manual, it states the 9xx are 9 speed only and the 8xx are 8 speed max. So who can tell?
You sure it isn’t a PC48? I can’t find a PC40 in their manuals. But if a 48, you can compare the specs:
