4,5,6,7-Tetraphenyl-2,3,3a,7a-tetrahydro-indene is a complex organic compound characterized by its unique molecular structure. It features a tetrahydro-indene core, which is a type of hydrocarbon with a partially saturated ring structure. The molecule is adorned with four phenyl groups (C6H5-), which are benzene rings, attached at the 4, 5, 6, and 7 positions of the indene ring. This arrangement of phenyl groups significantly influences the compound's physical and chemical properties, such as its stability, reactivity, and potential applications in areas like materials science and organic chemistry. The compound's specific structure and the presence of phenyl groups suggest that it may exhibit interesting electronic and steric properties, which could be relevant for its use in the synthesis of more complex molecules or as a component in advanced materials.
The CAS Registry Mumber 1642-75-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 2 respectively; the second part has 2 digits, 7 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1642-75: (6*1)+(5*6)+(4*4)+(3*2)+(2*7)+(1*5)=77 77 % 10 = 7 So 1642-75-7 is a valid CAS Registry Number.
