1,2,3,4,9,9-hexaphenyl-1,4-dihydro-1,4-episilano-naphthalene is a complex organic compound characterized by its unique molecular structure. It features a naphthalene core, which is a type of hydrocarbon with two fused benzene rings. The naphthalene in 1,2,3,4,9,9-hexaphenyl-1,4-dihydro-1,4-episilano-naphthalene is modified by the addition of six phenyl groups, which are benzene rings with a hydrogen atom replaced by a carbon-carbon single bond. The term "1,4-dihydro" indicates that there are two hydrogen atoms added to the 1 and 4 positions of the naphthalene ring, which affects its electronic properties and reactivity. The "episilano" part of the name suggests a specific arrangement or isomerism related to silicon atoms, although the exact nature of this is not standard in chemical nomenclature and might refer to a non-standard or proprietary modification. 1,2,3,4,9,9-hexaphenyl-1,4-dihydro-1,4-episilano-naphthalene is likely to be of interest in materials science and organic chemistry due to its potential applications in areas such as luminescent materials or as a component in advanced polymers, given the presence of multiple phenyl groups which can influence its electronic and optical properties.
The CAS Registry Mumber 1762-11-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,6 and 2 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1762-11: (6*1)+(5*7)+(4*6)+(3*2)+(2*1)+(1*1)=74 74 % 10 = 4 So 1762-11-4 is a valid CAS Registry Number.
