The Schwartz distribution space becomes a topological quasi-*-algebra with the distinguished subspace , if one defines the so-called twisted product in it. In the paper it is pointed out that the Weyl quantization IV(/) is an isomorphism of this topological quasi-*-algebra onto the topological quasi-*-algebra of all linear continuous operators of in . Furthermore, the problem of the extensions of the multiplications in these quasi-*-algebras is discussed.
