Check Digit Verification of cas no

The CAS Registry Mumber 212373-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,3,7 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 212373-72:
(8*2)+(7*1)+(6*2)+(5*3)+(4*7)+(3*3)+(2*7)+(1*2)=103
103 % 10 = 3
So 212373-72-3 is a valid CAS Registry Number.

Construction of the azepinoindole core tricycle of the Stemona alkaloids

Rigby, James H.,Laurent, Stephane,Cavezza, Alexandre,Heeg, Mary Jane

, p. 5587 - 5591 (2007/10/03)

The azepinoindole substructure common to a number of Stemona alkaloids is constructed by employing a 7-endo radical cyclization of a readily available N-alkylated hydroindolone substrate. The indolone precursors are prepared via [1 + 4] cycloaddition between a vinyl isocyanate and either dimethoxycarbene or cyclohexylisocyanide.
