1,8-Diphenyl-1,2-dihydro-naphthalin-1,2-dicarbonsaeure-dimethylester, also known as 1,8-diphenyl-1,2-dihydro-naphthalene-1,2-dicarboxylic acid dimethyl ester, is a complex organic compound with the chemical formula C23H20O4. It is a derivative of naphthalene, featuring two phenyl groups attached to the 1 and 8 positions of the naphthalene core. The molecule also contains a dihydro structure, indicating the presence of a single bond between the two carbon atoms that would otherwise be part of the naphthalene ring. The two carboxylic acid groups are located at the 1 and 2 positions and are esterified with methanol, resulting in dimethyl esters. 1,8-Diphenyl-1,2-dihydro-naphthalin-1,2-dicarbonsaeure-dimethylester is characterized by its aromatic structure and is used in various chemical syntheses, particularly in the production of pharmaceuticals and other organic compounds.

7775-74-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7775-74-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,7 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.Calculate Digit Verification of CAS Registry Number 7775-74:
(6*7)+(5*7)+(4*7)+(3*5)+(2*7)+(1*4)=138
138 % 10 = 8
So 7775-74-8 is a valid CAS Registry Number.
