   Instead, I would bring the floor up to the flange - sit the toilet on some kind of small platform, marble or whatever would match your floor.

   But that's just me, I would always try and avoid cutting a cast iron drainpipe. 

   My current toilet re-do is on a relatively not ugly white oak platform as I had ripped up the 50's tile flloor down to the original 20's wood floor, a good 1.25 inches lower.

   you can cut it with a sawzall, patience and some extra blades, but then you need to figure out how to add a flange ..

   Use an angle grinder with a metal cutting wheel.  You can make a clean cut and there are flanges that fit inside the pipe and expand a rubber ring to seal it.

    

   The platform method is also a good way to go.

   sawzall and a Lennox cast iron cutting blade. Not all cast iron cuts the same, I have cut thru a 4" pipe in under 2 minutes and sometimes it takes 10 minutes.Hard to fathom why,same type blade ,usually new or lightly used.

   For your information the toilet flange should sit flush with your finished floor, that means the pipe should be approx. 1/4 inch above finish.  If you have a flange on the pipe remove that first, this can be done with a cut-off wheel on a 4 1/2 inch grinder, [if you have one], once you have the flange off proceed to cut the pipe, same tool; you don't have to worry about cutting too short cut it flush if its easier.  Next thing is to go to a plumbing supply and get a c.i. flange that goes on the outside of the pipe with a rubber seal that has bolts that tighten it to the pipe. This pertains to you having a lead joint at the flange?  Luck

   It's done. I would have used the grinder if I had read your message first. I used a silsaw to cut slots to the concrete floor, a chisel to mark a line inside and a hammer to break the cast pipe off. The steal flange broke off with a hammer also. Used a flange with the rubber compression ring inside. Worked great.
