N-(4-methylphenyl)-4-nitronaphthalene-1,8-dicarboximide is a complex organic compound with the molecular formula C19H13N2O5. It is characterized by a naphthalene core, which is a fused ring system consisting of two benzene rings, with a nitro group (-NO2) attached to one of the rings. The compound also features a 4-methylphenyl group (a benzene ring with a methyl group attached) and two carboxylic acid groups (-COOH), one attached to each end of the naphthalene. This chemical structure endows the compound with specific properties, such as its potential use in the synthesis of dyes, pharmaceuticals, or other organic materials. The compound's reactivity and stability can be influenced by the presence of the nitro group, which can participate in various chemical reactions, and the carboxylic acid groups, which can form salts or esters.

129-23-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 129-23-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129-23:
(5*1)+(4*2)+(3*9)+(2*2)+(1*3)=47
47 % 10 = 7
So 129-23-7 is a valid CAS Registry Number.
