The 112 is the LSA... lobe separation angle. There is normally another number after that for ICL which for these cams would typically be 108-ish, but that number is missing here.
That last (missing) number is the ICL as the cam grinder grinds the cam relative to the standard sprockets and keys on cam and crank. A 108 ICL number would indicate that the cam is advanced 4 degrees if you installed it dot-to-dot. (112-108 = 4 degrees advance). So if you install it at ICL=104, then that is 4 more degrees advanced from the dot-to-dot installation, which would be at the +4 position for the crank sprocket of one of those settable cam timing chain sets.
