Check Digit Verification of cas no

The CAS Registry Mumber 84432-52-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,4,3 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 84432-52:
(7*8)+(6*4)+(5*4)+(4*3)+(3*2)+(2*5)+(1*2)=130
130 % 10 = 0
So 84432-52-0 is a valid CAS Registry Number.

Synthesis of Polynitro Compounds. Hexasubstituted Benzenes

Atkins, Ronald L.,Hollins, Richard A.,Wilson, William S.

, p. 3261 - 3266 (2007/10/02)

The synthesis of the three isomeric aminotetranitrotoluenes by nitration of an appriopriate aminodinitrotoluene is presented, and the apparent ipso nitration of 4-amino-2,6-dinitrotoluene to give pentanitroaniline, is also discussed.The oxidation of the isomeric aminotetranitrotoluenes to pentanitrotoluene is described, as is the ammonolysis of pentanitroaniline and of pentanitrotoluene.

Methods of preparing pentanitrotoluene

-

, (2008/06/13)

Pentanitrotoluene is prepared by a method which comprises preparing an amdinitrotoluene from a precursor of either TNT or 2,5-dinitro-3-methylbenzoic acid, nitrating the aminodinitrotoluene to produce a nitramine intermediate, converting the nitramine intermediate to an aminotetranitrotoluene and oxidizing the aminotetranitrotoluene with peroxydisulfuric acid to pentanitrotoluene. Pentanitrotoluene is an explosive.
