83621-03-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83621-03-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,6,2 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83621-03:
(7*8)+(6*3)+(5*6)+(4*2)+(3*1)+(2*0)+(1*3)=118
118 % 10 = 8
So 83621-03-8 is a valid CAS Registry Number.

Discovery of novel 1-azoniabicyclo[2.2.2]octane muscarinic acetylcholine receptor antagonists

supporting information; experimental part, p. 2493 - 2505 (2010/03/04)

A novel 4-hydroxyl(diphenyl)methyl substituted quinuclidine series was discovered as a very promising class of muscarinic antagonists. The structure-activity relationships of the connectivity of the diphenyl moiety to the quinuclidine core and around the ring nitrogen side chain are described. Computational docking studies using an homology model of the M3 receptor readily explained the observed structure-activity relationship of the various compounds. Compound 14o was identified as a very potent, slowly reversible M3 antagonist with a very long in vivo duration of bronchoprotection.
