Check Digit Verification of cas no

The CAS Registry Mumber 120052-37-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,0,5 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 120052-37:
(8*1)+(7*2)+(6*0)+(5*0)+(4*5)+(3*2)+(2*3)+(1*7)=61
61 % 10 = 1
So 120052-37-1 is a valid CAS Registry Number.

LC-NMR and LC-MS analysis of 2,3,10,11-oxygenated protoberberine metabolites in Corydalis cell cultures

, p. 1229 - 1238 (2007/10/03)

The metabolism of 2,3,10,11-oxygenated protoberberine alkaloids was studied in cell cultures of Corydalis species. Without prior isolation, the structures of the metabolites were determined by LC-MS and LC-NMR analyses. Tetrahydropseudocoptisine α-N-metho salt, pseudoprotopine, and pseudomuramine were identified for the first time, and preliminary evidence for metabolic pathways to the formation of these alkaloids were obtained.
