Check Digit Verification of cas no

The CAS Registry Mumber 1311471-04-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,1,4,7 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1311471-04:
(9*1)+(8*3)+(7*1)+(6*1)+(5*4)+(4*7)+(3*1)+(2*0)+(1*4)=101
101 % 10 = 1
So 1311471-04-1 is a valid CAS Registry Number.

Gold-catalyzed oxidation of arylallenes: Synthesis of quinoxalines and benzimidazoles

Cui, Dong-Mei,Zhuang, Dan-Wen,Chen, Ying,Zhang, Chen

, p. 860 - 865 (2011)

A gold-catalyzed oxidation of arylallenes to form α-diketones and aldehydes in good yields is presented. Further directed synthesis of quinoxalines and benzimidazoles, via the condensation of the resulting α-diketones and aldehydes with benzene-1,2-diamine, was achieved in high yields.
