I said (and you snipped):
better is "a definite extension of the region of real numbers into the infinitely large".

You are making no sense.

And you have forgotten that you claim Cantor uses multiplication on reals which are not also cardinals.

Does 3.14159... appear in Cantor's numberclasses, then?

As I said before, and you have deleted:
"And what does this give? an ordered set; but no multiplication defined here, of course! "
Still not a single example of Cantor multiplying a transfinite number with anything other than another ordinal/cardinal.
