1,2,3,4-Tetraphenyl-5,6-dimethyl-calicen is a complex organic compound characterized by its unique structure, which consists of a calicene core with four phenyl groups attached to the 1, 2, 3, and 4 positions, and two methyl groups at the 5 and 6 positions. Calicene is a bowl-shaped hydrocarbon with a central cavity, and the presence of the phenyl and methyl groups significantly influences its physical and chemical properties. 1,2,3,4-Tetraphenyl-5,6-dimethyl-calicen is of interest in the field of organic chemistry, particularly for its potential applications in materials science and as a building block for more complex molecular structures. The synthesis and study of such compounds can provide insights into the behavior of large aromatic systems and their interactions with other molecules.
The CAS Registry Mumber 7178-47-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,7 and 8 respectively; the second part has 2 digits, 4 and 7 respectively. Calculate Digit Verification of CAS Registry Number 7178-47: (6*7)+(5*1)+(4*7)+(3*8)+(2*4)+(1*7)=114 114 % 10 = 4 So 7178-47-4 is a valid CAS Registry Number.
