Is C[S@](=O)CC
tetracoordinate?
Likewise C1[N@](O1)CC
Is
C[S@](=O)CC
tetracoordinate?
No, but it is tetravalent.
Likewise
C1[N@](O1)CC
No.
It may be a good idea to define the term, or just replace it with "an atom having four neighbors."
Discussion of stereo descriptors should indicate that it is an error to assign one to anything other than a tetracoordinate atom.
