1,2,3,4,5-Pentaphenyl-1,3-cyclohexadien is a complex organic compound characterized by a cyclohexadien ring structure with five phenyl groups attached to it. This molecule is composed of a six-carbon ring with alternating double bonds, and each carbon atom, except for the ones involved in the double bonds, is connected to a phenyl group. The compound is known for its unique electronic properties and is of interest in the field of organic chemistry, particularly in the study of aromaticity and the effects of conjugation. It is a challenging synthetic target due to the steric hindrance caused by the multiple phenyl groups, which can lead to interesting conformational preferences and electronic effects. The compound's structure and properties make it a subject of study for understanding the behavior of large, conjugated systems in organic chemistry.

2858-03-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2858-03-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,5 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.Calculate Digit Verification of CAS Registry Number 2858-03:
(6*2)+(5*8)+(4*5)+(3*8)+(2*0)+(1*3)=99
99 % 10 = 9
So 2858-03-9 is a valid CAS Registry Number.
