Calculate Digit Verification of CAS Registry Number 72323-70:
(7*7)+(6*2)+(5*3)+(4*2)+(3*3)+(2*7)+(1*0)=107
107 % 10 = 7
So 72323-70-7 is a valid CAS Registry Number.

Adrievskii, A. M.,Poplavskii, A. N.,Dyumaev, K. M.

, p. 1195 - 1198 (2007/10/02)

Methods were developed for the synthesis of polynitro-substituted 2-carboxybiphenyls.During the nitration of 2-carboxybiphenyl under rigorous conditions or during the heating of nitro-substituted 2-carboxybiphenyls in concentrated sulfuric acid or high-strength oleum decarboxylation and cyclization occur with the formation of nitro-substituted biphenyls and fluorenone.
