21371-44-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21371-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,7 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21371-44:
(7*2)+(6*1)+(5*3)+(4*7)+(3*1)+(2*4)+(1*4)=78
78 % 10 = 8
So 21371-44-8 is a valid CAS Registry Number.

Reduction of Aromatic Nitro Compounds by Ethylenediamine. A New Selective Reagent for the Synthesis of Symmetric Azo Compounds

Chung, T. F.,Wu, Y. M.,Cheng, C. H.

, p. 1215 - 1217 (2007/10/02)

Ethylenediamine selectively reduces aromatic nitro compounds RC6H4NO2 (R = H, m-CH3, p-CH3, and m-Ph) at 150 deg C to symmetric azo compounds RC6H4N=NC6H4R in good yield but does not reduce their ortho-substituted analogues.The diamine does not react with o- or p-nitroanilines but reduces the meta isomer to 1,3-diaminobenzene and 3,3'-diaminoazobenzene.Its reaction with o- and p-halonitrobenzenes gives substitution products H2NCH2CH2NHC6H4NO2.Nitrosobenzene is reduced to aniline and azobenzene, while α-nitroso-β-naphthol is converted to 1,4-phenanthroline.Among a variety of other amines tested, only 1,3-propylenediamine reduces nitrobenzene to azobenzene.A mechanism for the reaction is proposed.
