Calculate Digit Verification of CAS Registry Number 681851-33:
(8*6)+(7*8)+(6*1)+(5*8)+(4*5)+(3*1)+(2*3)+(1*3)=182
182 % 10 = 2
So 681851-33-2 is a valid CAS Registry Number.

Properties and Reactions of Substituted 1,2-Thiazetidine 1,1-Dioxides: Chiral Mono- and Bicyclic 1,2-Thiazetidine 1,1-Dioxides from α-Amino Acids

Meinzer, Alexandra,Breckel, Andrea,Thaher, Bassam Abu,Manicone, Nico,Otto, Hans-Hartwig

, p. 90 - 105 (2007/10/03)

New chiral mono- and bicyclic β-sultams, valuable building blocks for drug synthesis, have been prepared from L-Ala, L-Val, L-Leu, L-Ile, L-Phe, L-Cys, L-Ser, L-Thr, and D-penicillamine by transformation of the COOH group into a methylsulfonyl chloride function, followed by cyclization under basic conditions. Selected properties, derivatives, and reactions of the β-sultams are described.
