"9-(2,3,4,5-Tetraphenyl-cyclopenta-1,3-dienylmethylene)-9H-fluorene" is a complex organic compound characterized by its unique molecular structure. It features a fluorene core, which is a type of polycyclic aromatic hydrocarbon, with a cyclopenta-1,3-dienylmethylene group attached to the 9-position. This dienylmethylene group is further adorned with four phenyl rings, making the molecule highly conjugated and potentially useful in the study of organic electronics and materials science. The compound's structure suggests it may exhibit interesting photophysical properties due to the extended conjugation and the presence of multiple aromatic rings. It is likely to be a subject of research in fields such as organic synthesis, molecular design, and potentially in the development of new materials with specific optical or electronic properties.
The CAS Registry Mumber 4600-79-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,0 and 0 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 4600-79: (6*4)+(5*6)+(4*0)+(3*0)+(2*7)+(1*9)=77 77 % 10 = 7 So 4600-79-7 is a valid CAS Registry Number.
