861782-46-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 861782-46-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,7,8 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 861782-46:
(8*8)+(7*6)+(6*1)+(5*7)+(4*8)+(3*2)+(2*4)+(1*6)=199
199 % 10 = 9
So 861782-46-9 is a valid CAS Registry Number.

KINETICS AND MECHANISM OF N-NITRATION. IX. EFFECT OF BASICITY ON THE RATE OF N-NITRATION OF PRIMARY AROMATIC AMINES WITH AQUEOUS NITRIC ACID. kINETIC METHOD FOR DETERMINATION OF THE BASICITY OF POLYNITROANILINES

Morozov, A. V.,Kuznetsov, L. L.,Selivanov, V. F.,Gidaspov, B. V.

, p. 651 - 654 (2007/10/02)

The rate of N-nitration of nine primary aromatic amines in aqueous nitric acid was measured by a spectrophotometric method.The dependence of the logarithms of the rate constans for the nitration of the amines on their basicity was refined.The basicities of 2,4,5,6-tetranitro-3-bromo-, 2,4,5,6-tetranitro-3-chloro-, and 2,3,4,5,6-pentanitroaniline were determined by means of the obtained relationship (pKBH+ -11.6, -12.0 and -15.5 repectively).
