Check Digit Verification of cas no

The CAS Registry Mumber 2198-74-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,9 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2198-74:
(6*2)+(5*1)+(4*9)+(3*8)+(2*7)+(1*4)=95
95 % 10 = 5
So 2198-74-5 is a valid CAS Registry Number.

Chemoselective reductive coupling of nitroarenes with magnesium in methanol via single electron transfer

Khurana, Jitender M.,Ray, Abhijit

, p. 407 - 410 (1996)

A chemoselective reductive coupling of nitroarenes using magnesium in methanol has been reported at ambient temperature. While the cyano, formyl, methoxycarbonyl, methyl, methoxy, phenyl, amino, and chloro groups are unaffected, iodo and bromo groups undergo dehalogenation but in a slower reaction than the coupling of nitro group. The coupling is believed to be proceeding via SET from Mg to nitroarenes.
