Check Digit Verification of cas no

The CAS Registry Mumber 145103-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,1,0 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 145103-20:
(8*1)+(7*4)+(6*5)+(5*1)+(4*0)+(3*3)+(2*2)+(1*0)=84
84 % 10 = 4
So 145103-20-4 is a valid CAS Registry Number.

Synthesis of Dibenzoquinolizines - A New Entry to Protoberberines

Reimann, Eberhard,Benend, Helmut

, p. 939 - 948 (2007/10/02)

A novel synthesis to prepare dibenzo-8-quinolizinones 8 is reported using the intramolecular cyclisation of the benzylated Reissert compounds 6 for the key step.Methylation of 8 by methyllithium gives partial deoxygenated coralynes 10 which in turn can be reduced by NaBH4 yielding the 8-methyltetrahydro-protoberberines 11.The structures are assigned by NMR-spectroscopy. Keywords.Reissert compounds; Intramolecular cyclisation; Dibenzo-8-quinolizinones; Deoxygenated coralynes; 8-Methyltetrahydro-protoberberines.
