The structure of the molecule can be visualized as a chain of three silicon atoms, each bonded to an oxygen atom, with the phenyl and methyl groups attached to the silicon atoms. 1,1,3,5,5-pentamethyl-1,3,5-triphenyl-trisiloxane is known for its thermal stability and resistance to oxidation, making it useful in various applications such as lubricants, sealants, and high-temperature-resistant materials.
The CAS Registry Mumber 80-14-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 0 respectively; the second part has 2 digits, 1 and 4 respectively. Calculate Digit Verification of CAS Registry Number 80-14: (4*8)+(3*0)+(2*1)+(1*4)=38 38 % 10 = 8 So 80-14-8 is a valid CAS Registry Number.
