1-Phenyl-3,4-dihydro-naphthalin-3,4-dicarbonsaeure, also known as 1-phenyl-3,4-dihydro-1,2,3,4-tetrahydro-naphthalene-3,4-dicarboxylic acid, is a complex organic compound with the molecular formula C18H16O4. It is a derivative of naphthalene, featuring a phenyl group attached to a dihydro-naphthalene core, with two carboxylic acid groups at the 3 and 4 positions. 1-Phenyl-3,4-dihydro-naphthalin-3,4-dicarbonsaeure is of interest in organic chemistry and may have potential applications in the synthesis of pharmaceuticals, dyes, and other specialty chemicals due to its unique structure and reactivity. The compound's properties, such as solubility and stability, can be influenced by the presence of the phenyl group and the dihydro-naphthalene ring system, making it a subject of study for chemists exploring the effects of structural modifications on molecular behavior.
The CAS Registry Mumber 7775-71-5 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 1 respectively. Calculate Digit Verification of CAS Registry Number 7775-71: (6*7)+(5*7)+(4*7)+(3*5)+(2*7)+(1*1)=135 135 % 10 = 5 So 7775-71-5 is a valid CAS Registry Number.
