4,5,6,7-Tetraphenyl-3a,7a-dihydro-1H-indene is a complex organic compound characterized by its unique molecular structure, which features a central indene ring system with four phenyl groups attached at positions 4, 5, 6, and 7. 4,5,6,7-Tetraphenyl-3a,7a-dihydro-1H-indene is a derivative of the parent hydrocarbon, indene, and is known for its rigid and planar structure due to the presence of the dihydro functional groups at positions 3a and 7a. The tetraphenyl substitution imparts significant steric hindrance and affects the compound's physical properties, such as melting point and solubility. It is typically synthesized through organic chemistry methods and is of interest in the field of synthetic chemistry for its potential applications in materials science and as a precursor in the synthesis of more complex molecules.
The CAS Registry Mumber 1180-31-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 0 respectively; the second part has 2 digits, 3 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1180-31: (6*1)+(5*1)+(4*8)+(3*0)+(2*3)+(1*1)=50 50 % 10 = 0 So 1180-31-0 is a valid CAS Registry Number.
