131792-46-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131792-46-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,7,9 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131792-46:
(8*1)+(7*3)+(6*1)+(5*7)+(4*9)+(3*2)+(2*4)+(1*6)=126
126 % 10 = 6
So 131792-46-6 is a valid CAS Registry Number.

Isomeric Monomethyl Ether Derivatives of (RS)-9,10-Dihydroxyaporphine ("Isoapomorphine") as Possible Products of Metabolism by Catechol-O-methyltransferase

Cannon, Joseph G.,Qijie, Pang

, p. 1079 - 1082 (2007/10/02)

The isomeric monomethyl ether derivatives of (RS)-9,10-dihydroxyaporphine ("isoapomorphine") were synthesized unequivocally as possible metabolites in catechol-O-methyltransferase (COMT) mediated O-methylation reactions.In vitro incubation studies revealed that isoapomorphine is not a substrate for the COMT using experimental conditions under which apomorphine (10,11-dihydroxyaporphine) is converted in high yield into its 10-methyl ether, apocodeine.The in vivo dopaminergic inactivity of isoapomorphine (as compared with that of apomorphine) seems to be due to factors other than metabolic inactivation by COMT.
