The CAS Registry Mumber 1238333-74-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,8,3,3 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1238333-74:
(9*1)+(8*2)+(7*3)+(6*8)+(5*3)+(4*3)+(3*3)+(2*7)+(1*4)=148
148 % 10 = 8

General method for the synthesis of substituted phenanthridin-6(5H)-ones using a KOH-mediated anionic ring closure as the key step

Dubost, Emmanuelle,Magnelli, Rosa,Cailly, Thomas,Legay, Rémi,Fabis, Frédéric,Rault, Sylvain

experimental part, p. 5008 - 5016 (2010/08/13)

Substituted phenanthridin-6(5H)-ones were obtained in a two-step procedure involving a Suzuki cross-coupling reaction followed by a KOH-mediated anionic ring closure. The influence of the nature and the position of the substituents on the cyclization step were studied. This methodology offers a general and practical route to diversely substituted phenanthridin-6(5H)-ones.
