No, the digits of pi are not random. They can be generated using a very short program, and that's the very definition of non-random.
If, by "not random" you mean the same sequence would be generated each time, I would agree. If you really mean to say that the digits of pi are not random, mathematicians at Purdue, Berkeley, and elsewhere appear to have concluded, at best, that pi's randomness is an open question. I can find no reference that indicates that (in the sequence of digits of pi) the digit following any finite sequence can be predicted, which is one indication of randomness.
With regard to the OP:
is there anyway to use this as a random number generator?
If you need to generate a number that cannot be predicted before it's generated (perhaps the intent of Alvaro's statement), that's problematic.
For instance, assuming that the digits of pi are random (as mentioned above, there are questions in that regard,) you would have to develop an algorithm to randomly select a sequence from those digits. Therein lies the rub. A random selection algorithm such as that would either be predictable or would need yet another such supporting algorithm.
