noticed a pretty good leak yesterday at my rental. It was in the basement main drain Stack. I went to the 2nd floor and was able to access the stack there and the water was dripping on that from up above so the leak has to be between the 3rd and 2nd floors. The issue I have is how can there be a leak when the water was not running?? No one was home at the time? Should I replace the cast iron stack or does this mean there is a clog?

Maybe the area around/under the pipe leak is saturated (think wet drywall) and that's what your seeing dripping.

You will probably find that a toilet on the third floor is running, possibly because of a defective fill valve.
Are you sure it's not a leak on the water supply? That would be more likely.
If you aren't running water it's normally okay. Unless like mentioned above you have a leaking flapper on a toilet upstairs.
