877172-04-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 877172-04-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,7,1,7 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 877172-04:
(8*8)+(7*7)+(6*7)+(5*1)+(4*7)+(3*2)+(2*0)+(1*4)=198
198 % 10 = 8
So 877172-04-8 is a valid CAS Registry Number.

Palladium-catalyzed intramolecular N-arylation of heteroarenes: A novel and efficient route to benzimidazo[1,2-a]quinolines
Venkatesh,Sundaram,Ila,Junjappa
, p. 1280 - 1283 (2007/10/03)
An efficient new route for the synthesis of benzimidazo-1,2-a]quinolines has been developed via the palladium-catalyzed intramolecular Buchwald-Harwtig aryl amination of newly synthesized 2-(2′-bromoanilino)quinolines.
