Check Digit Verification of cas no
The CAS Registry Mumber 34379-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,3,7 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 34379-04:
(7*3)+(6*4)+(5*3)+(4*7)+(3*9)+(2*0)+(1*4)=119
119 % 10 = 9
So 34379-04-9 is a valid CAS Registry Number.

Lead-Catalyzed Synthesis of Azo Compounds by Ammonium Acetate Reduction of Aromatic Nitro Compounds
Srinivasa,Abiraj,Gowda, D. Channe
, p. 4221 - 4227 (2007/10/03)
Lead/ammonium acetate is a convenient reagent for the reduction of aromatic nitro compounds to the corresponding symmetrically substituted azo compounds. Various azo compounds containing additional reducible substituents such as halogen, nitrile, acid, phenol, ester, methoxy, etc., functions have been synthesized in a single step by the use of this reagent. The conversion is reasonably fast, clean, high yielding and occurs at room temperature in methanol.
Oxidations of Aromatic Amines by Superoxide Ion

Superoxide ion acts as a mild and highly selective oxidizing agent for aromatic amines.Aniline and α-naphthylamine were not oxidized, but β-naphthylamine formed dibenzophenazine, dibenzophenazine and 2,2'-azonaphthalen-1-ol. o- and p-Diamines are oxidized to diaminoazobenzenes but m-diamines are unreactive.Similarly o- and p-aminophenols are oxidized to dihydroxyazobenzenes but m-aminophenols are unaffected, and o-mercaptoaniline forms the disulfide.The oxidations are considered to be free-radical processes, initiated by hydrogen abstraction by superoxide from the substrates.The biological significance of the results is discussed.

Potassium superoxide is a selective oxidant for aromatic compounds with the order of susceptibility of substituent groups being -SH>-NH2-OH. Only o- and p- disubstituted amines and phenols are oxidized but monosubstituted thiols react.
