The CAS Registry Mumber 247049-85-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,0,4 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 247049-85:
(8*2)+(7*4)+(6*7)+(5*0)+(4*4)+(3*9)+(2*8)+(1*5)=150
150 % 10 = 0
So 247049-85-0 is a valid CAS Registry Number.

Acylation of o-Phenylenediamine with 4-Cyclohexene-1,2-dicarboxylic Anhydride

Salakhov, M. S.,Umaeva, V. S.,Salakhova, Ya. S.,Idrisova, S. Sh.

, p. 397 - 401 (2007/10/03)

Acylation of o-phenylenediamine with cis- and trans-4-cyclohexene-1,2-dicarboxylic anhydrides in acetone yields cis- and trans-3-(o-aminophenylaminocarbonyl)-4-cyclohexenecarboxylic acids which undergo intramolecular ring closure on heating in o-xylene or petroleum ether to form cis-N-(o-aminophenyl)-4-cyclohexene-1,2-dicarboximide. Heating of 3-(o-aminophenylaminocarbonyl)-4-cyclohexenecarboxylic acid in benzene in the presence of KU-2 cation exchanger (H form) leads to formation of a mixture of cis-N-(o-aminophenyl)-4-cyclohexene-1,2-dicarboximide and 6-(2-benzimidazolyl)-3-cyclohexenecarboxylic acid.
