Check Digit Verification of cas no
The CAS Registry Mumber 116-71-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 116-71:
(5*1)+(4*1)+(3*6)+(2*7)+(1*1)=42
42 % 10 = 2
So 116-71-2 is a valid CAS Registry Number.

Perylene derivatives formation in reaction of 3-bromobenzanthrone and 4-bromonaphthalic acid derivatives with a reduction system NiCl2 - 2,2′bipyridyl (or 1,10-phenathroline) - Zn

The reaction of 3-bromobenzanthrone and 4-bromonaphthalic acid derivatives with a reduction system NiCl2-2,2′bipyridyl (or 1,10-phenathroline)-Zn gives rise to compounds containing perylene fragment. Under similar conditions was established a possibility to transform substituted 1,1′-binaphthyls into the corresponding perylene derivatives.
