Check Digit Verification of cas no
The CAS Registry Mumber 3179-90-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,7 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3179-90:
(6*3)+(5*1)+(4*7)+(3*9)+(2*9)+(1*0)=96
96 % 10 = 6
So 3179-90-6 is a valid CAS Registry Number.

Dehydrogenations using benzofuroxan as oxidant
Patzold,Zeuner,Heyer,Niclas
, p. 281 - 288 (2007/10/02)
2-Arylsubstituted benzimidazoles, quinoxalines, in 3,5-position substituted 2,6-dimethylpyridines, and 1,4-bis(alkylamino)-9,10-anthracenediones are easily prepared under mild conditions by means of benzofuroxan as oxidant. Thus, the preparation of 2-arylbenzimidazoles succeeds in acetonitrile at 50°C in yields of 65 to 78%.
