Check Digit Verification of cas no

The CAS Registry Mumber 1133726-80-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,3,7,2 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1133726-80:
(9*1)+(8*1)+(7*3)+(6*3)+(5*7)+(4*2)+(3*6)+(2*8)+(1*0)=133
133 % 10 = 3
So 1133726-80-3 is a valid CAS Registry Number.

Novel synthesis of pyrido[2,1-a]isoindoles via a three-component assembly involving benzynes

Xie, Chunsong,Zhang, Yuhong,Xu, Peixin

, p. 3115 - 3120 (2008)

A novel three-component assembly involving benzynes has been developed for the synthesis of pyrido[2,1-a]isoindoles in moderate yields. Reaction conditions have been optimized and the scope of the reaction has been studied. A plausible mechanism has been proposed to account for the three-component reaction.
