Calculate Digit Verification of CAS Registry Number 203180-34:
(8*2)+(7*0)+(6*3)+(5*1)+(4*8)+(3*0)+(2*3)+(1*4)=81
81 % 10 = 1
So 203180-34-1 is a valid CAS Registry Number.

Boyle, Craig D,Chackalamannil, Samuel,Chen, Lian-Yong,Dugar, Sundeep,Pushpavanam, Pradeep,Billard, William,Binch III, Herbert,Crosby, Gordon,Cohen-Williams, Mary,Coffin, Vicki L,Duffy, Ruth A,Ruperto, Vilma,Lachowicz, Jean E

Benzylidene ketal derivatives were investigated as selective M2 receptor antagonists for the treatment of Alzheimer's disease. Compound 10 was discovered to have subnanomolar M2 receptor affinity and 100-fold selectivity against other muscarinic receptors. Also, 10 demonstrated in vivo efficacy in rodent models of muscarinic activity and cognition. (C) 2000 Elsevier Science Ltd.
