Check Digit Verification of cas no

The CAS Registry Mumber 1238735-10-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,8,7,3 and 5 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1238735-10:
(9*1)+(8*2)+(7*3)+(6*8)+(5*7)+(4*3)+(3*5)+(2*1)+(1*0)=158
158 % 10 = 8
So 1238735-10-8 is a valid CAS Registry Number.

One-pot palladium-catalyzed synthesis of selectively substituted phenanthridines by sequential aryl-aryl and heck couplings, aza-michael and retro-mannich reactions

Della Ca, Nicola,Motti, Elena,Mega, Antonio,Catellani, Marta

, p. 1451 - 1454 (2010)

A catalytic synthesis of selectively substituted phenanthridines is achieved through a reaction sequence involving palladium/norbornene-catalyzed unsymmetrical aryl-aryl and Heck couplings followed by aza-Michael and retro-Mannich reactions. In spite of the many steps involved the method is very simple and allows the formation of selectively substituted phenanthridines under mild conditions in a straightforward one-pot reaction starting from readily available aryl iodides and bromides.
