Check Digit Verification of cas no

The CAS Registry Mumber 892804-31-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,2,8,0 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 892804-31:
(8*8)+(7*9)+(6*2)+(5*8)+(4*0)+(3*4)+(2*3)+(1*1)=198
198 % 10 = 8
So 892804-31-8 is a valid CAS Registry Number.

The palladium-catalyzed preparation of condensed tetracyclic heterocycles and their application to the synthesis of rac-mangochinine

Vincze, Zoltan,Biro, A. Beatrix,Csekei, Marton,Timari, Geza,Kotschy, Andras

, p. 1375 - 1385 (2007/10/03)

Dihydroisoquinoline derivatives and their analogues, prepared by the Bischler-Napieralsky reaction, were converted to their indole-fused derivatives. Scope and limitations of the palladium-catalyzed reaction, proceeding through the tautomeric enamine forms of these compounds, were studied and the process was extended to the preparation of racemic mangochinine.
