From what I've found, 45-50, which is better than the requirements for diesel fuel in the US (40 cetane number -- different than cetane index -- see the wikipedia article). Depends on the source and condition, etc.
Biodiesels are higher, and burn cleaner due to their homogenous nature. Diesel fuel is a distillate, so it has a small amount of very heavy stuff that never burns properly.
