Calculate Digit Verification of CAS Registry Number 109972-62:
(8*1)+(7*0)+(6*9)+(5*9)+(4*7)+(3*2)+(2*6)+(1*2)=155
155 % 10 = 5
So 109972-62-5 is a valid CAS Registry Number.

N-NITRATION OF PRIMARY AROMATIC AMINES BY POLYNITRO AND POLYNITROXY COMPOUNDS

Mayants, A. G.,Pyreseva, K. G.,Gordeichuk, S. S.

, p. 1900 - 1903 (2007/10/02)

The possibility of N-nitration of primary aromatic amines containing SO3H and COOH groups by polynitro compounds C(NO2)4, (O2N)3CC(NO2)3, CH3C(NO2)3, C(NO2)3CH2CH2CN, and C(NO2)3CH2CH2COOCH3 and by polynitroxy compounds C(CH2ONO2)4 and HOCH2C(CH2ONO2)3 was investigated.In the presence of alkaline agents tetranitromethane, hexanitroethane, and pentaerythritol tetranitrate nitrate para- and meta-substituted aromatic amines with the formation of the corresponding nitroamine salts.Ortho-substituted amines do not enter into this reaction.
