Check Digit Verification of cas no

The CAS Registry Mumber 31054-08-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,0,5 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 31054-08:
(7*3)+(6*1)+(5*0)+(4*5)+(3*4)+(2*0)+(1*8)=67
67 % 10 = 7
So 31054-08-7 is a valid CAS Registry Number.

Direct Amination. Part 2. Reaction of 2-Phenylindole with Primary Aromatic Amines. A Chemical and Electrochemical Investigation

Berti, Corrado,Greci, Lucedio,Andruzzi, Romano,Trazza, Antonio

, p. 607 - 610 (2007/10/02)

The reaction of 2-phenylindole with primary aromatic amines to form 2-phenyl-3-arylimino-3H-indoles, in the presence of N-chlorobenzotriazole, N-chloroisatin or lead tetraacetate, were also investigated by anodic oxidation.The chemical and electrochemical results suggest a mechanism involving an intermediate nitrenium ion, whose formation was demonstrated by an independent route.The reaction of 1-hydroxy-2-phenylindole with p-anisidine to form 2-phenyl-3-p-methoxyphenylimino-3H-indole 1-oxide, previously studied under anodic oxidation is here described in the presence of N-chlorobenzotriazole.
