The CAS Registry Mumber 185304-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,3,0 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 185304-90:
(8*1)+(7*8)+(6*5)+(5*3)+(4*0)+(3*4)+(2*9)+(1*0)=139
139 % 10 = 9
So 185304-90-9 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.
