4,5,6,7-Tetraphenyl-indan is an organic compound characterized by its unique molecular structure, which consists of an indan (a seven-membered ring with a methyl group attached) core that is substituted with four phenyl groups. 4,5,6,7-Tetraphenyl-indan is known for its rigid and planar structure, which arises from the steric hindrance caused by the phenyl groups. It is often used in the field of materials science, particularly in the study of molecular packing and the development of new organic materials with specific optical or electronic properties. The compound's stability and resistance to chemical reactions make it a valuable component in the synthesis of more complex organic molecules and in the creation of supramolecular assemblies.
The CAS Registry Mumber 1061-67-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,6 and 1 respectively; the second part has 2 digits, 6 and 7 respectively. Calculate Digit Verification of CAS Registry Number 1061-67: (6*1)+(5*0)+(4*6)+(3*1)+(2*6)+(1*7)=52 52 % 10 = 2 So 1061-67-2 is a valid CAS Registry Number.
