Check Digit Verification of cas no
The CAS Registry Mumber 145313-93-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,3,1 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 145313-93:
(8*1)+(7*4)+(6*5)+(5*3)+(4*1)+(3*3)+(2*9)+(1*3)=115
115 % 10 = 5
So 145313-93-5 is a valid CAS Registry Number.

Protoberberines from Reissert compounds, II: A new synthesis of 8-methyldibenzo[a,g]quinolizidines
Reimann,Renz
, p. 253 - 258 (2007/10/02)
The Reissert compounds 16 are benzylated by 2-bromomethylacetophenone dioxolane 14 to give the dihydroisoquinolines 5. Treatment of 5 with KOH yields the 1-benzylisoquinolines 6 which spontaneously form the deoxygenated coralynes 4 in acidic solution. 4a
