Calculate Digit Verification of CAS Registry Number 194421-59:
(8*1)+(7*9)+(6*4)+(5*4)+(4*2)+(3*1)+(2*5)+(1*9)=145
145 % 10 = 5
So 194421-59-5 is a valid CAS Registry Number.

Lactones, part 28: EPC-Synthesis, structure and pharmacology of 'lactonized' and 'lactamized' analogues of acetylcholine

Pieper,Trankle,Nieger,Mohr,Lehmann

, p. 15 - 21 (2007/10/02)

The enantiopure γ-aminomethyl-γ-butyrolactones (S)- and (R)-4a-d represent constrained analogues of acetylcholine, which were synthesized from D- or L-glutamic acid following two different routes. In addition, the corresponding lactames (S)- and (R)-10 were prepared by enantioselective synthesis. Only moderate activity was found at acetylcholine sites at the guinea pig atrium.
