The chemical compound "2-(2-<2,3,4,5-Tetraphenyl-fulven-yl-(6)>-vinyl)-1,3,4,5-tetraphenyl-cyclopentadien" is a complex, polycyclic aromatic hydrocarbon with a unique structure. It features a central cyclopentadien ring that is highly substituted with phenyl groups at the 1, 3, 4, and 5 positions. Additionally, a vinyl group is attached at the 2 position, which itself is connected to a 2,3,4,5-tetraphenyl-fulvene moiety. This fulvene group is a type of cyclopentadienone with a double bond, and its phenyl groups contribute to the overall stability and electronic properties of the molecule. The compound is characterized by its large, delocalized π-system, which is a result of the extensive conjugation across the molecule, and it is likely to exhibit interesting electronic and optical properties due to its highly conjugated and symmetrical structure.
The CAS Registry Mumber 4599-87-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,9 and 9 respectively; the second part has 2 digits, 8 and 7 respectively. Calculate Digit Verification of CAS Registry Number 4599-87: (6*4)+(5*5)+(4*9)+(3*9)+(2*8)+(1*7)=135 135 % 10 = 5 So 4599-87-5 is a valid CAS Registry Number.
