The chemical compound "2-(1-Butyloxy-α-ethoxy)-2,5,5,7-tetramethyl-7-phenyl-5,7-disila-octin-(3)" is a complex organosilicon molecule with a unique structure. It features a central octin ring, which is a type of cyclic alkane, with the molecular formula C21H40O2Si2. The compound is characterized by the presence of two silicon atoms (Si) in the ring, which are connected to form a disila-octin structure. The 7-phenyl group attached to the ring provides aromaticity, while the 2,5,5,7-tetramethyl groups contribute to the molecule's stability and hydrophobicity. The 1-butyloxy-α-ethoxy substituent at the 2-position introduces a hydroxyl group and an ethoxy group, which can participate in hydrogen bonding and solubility in polar solvents. 2-<1-Butyloxy-aethoxy>-2.5.5.7-tetramethyl-7-phenyl-5.7-disila-octin-(3) is of interest in materials science and organosilicon chemistry due to its potential applications in the synthesis of silicones and other specialty chemicals.
The CAS Registry Mumber 6983-96-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,8 and 3 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 6983-96: (6*6)+(5*9)+(4*8)+(3*3)+(2*9)+(1*6)=146 146 % 10 = 6 So 6983-96-6 is a valid CAS Registry Number.
