1,3-Bis-(trimethylsilyl)-2,2-diphenyl-4,4-dimethyl-cyclodisilazan is a complex organosilicon compound with the molecular formula C18H28N2Si2. It features a cyclodisilazane core, which consists of two silicon atoms connected to each other through a single bond, with each silicon atom also bonded to a trimethylsilyl group (SiMe3). Additionally, the compound has two phenyl groups (C6H5) attached to the central silicon atoms, and two methyl groups (CH3) at the 4,4-positions. This unique structure endows the compound with interesting properties, such as thermal stability and potential applications in materials science and organic synthesis.
The CAS Registry Mumber 5958-81-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,5 and 8 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 5958-81: (6*5)+(5*9)+(4*5)+(3*8)+(2*8)+(1*1)=136 136 % 10 = 6 So 5958-81-6 is a valid CAS Registry Number.
