1,1'-Biphenyl-6,6'-dinitro-2,2'-dicarboxylic acid dimethyl ester is a complex organic compound with the chemical formula C16H12N2O8. It is derived from biphenyl, a type of aromatic hydrocarbon, and features two nitro groups (-NO2) at the 6th position of each phenyl ring, and two carboxyl groups (-COOH) at the 2nd position, which are esterified with methanol to form dimethyl esters (-COOCH3). 1,1'-biphenyl-6,6'-dinitro-2,2'-dicarboxylic acid dimethyl ester is characterized by its yellow crystalline appearance and is known for its potential applications in the synthesis of dyes and pharmaceuticals. Due to its structural complexity and functional groups, it is a subject of interest in organic chemistry and material science research.
The CAS Registry Mumber 803-54-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,0 and 3 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 803-54: (5*8)+(4*0)+(3*3)+(2*5)+(1*4)=63 63 % 10 = 3 So 803-54-3 is a valid CAS Registry Number.
