3,2'-Diphenyl-terphenyl and 2-Phenyl-(3)-quater<4,3>phenyl are complex aromatic hydrocarbons with multiple phenyl rings. 3,2'-Diphenyl-terphenyl consists of three phenyl rings connected linearly, with the central ring having two phenyl groups attached to it. On the other hand, 2-Phenyl-(3)-quater<4,3>phenyl is a quaterphenyl derivative, featuring four phenyl rings arranged in a specific pattern, with the third ring having a phenyl group attached to it. Both compounds are characterized by their rigid, planar structures and exhibit unique electronic properties due to the extended conjugation across the phenyl rings. These chemicals are primarily of interest in academic research, particularly in the fields of materials science and organic chemistry, where their electronic and optical properties are studied for potential applications in advanced materials and devices.
The CAS Registry Mumber 3761-37-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,6 and 1 respectively; the second part has 2 digits, 3 and 7 respectively. Calculate Digit Verification of CAS Registry Number 3761-37: (6*3)+(5*7)+(4*6)+(3*1)+(2*3)+(1*7)=93 93 % 10 = 3 So 3761-37-3 is a valid CAS Registry Number.
