Tris(pentabromphenoxy)silan, also known as Bromowax, is a chemical compound with the formula C6H3Br5O3Si. It is a white crystalline solid that is used as a flame retardant, particularly in polystyrene and other plastics. The compound consists of a silicon atom bonded to three pentabromophenoxy groups, which are phenol molecules with five bromine atoms attached. Tris(pentabromophenoxy)silan is effective in reducing the flammability of materials due to the presence of bromine atoms, which can interfere with the combustion process. However, it has been classified as a persistent, bioaccumulative, and toxic substance, raising concerns about its environmental and health impacts. As a result, its use has been restricted or banned in some regions.
The CAS Registry Mumber 17199-05-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,1,9 and 9 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 17199-05: (7*1)+(6*7)+(5*1)+(4*9)+(3*9)+(2*0)+(1*5)=122 122 % 10 = 2 So 17199-05-2 is a valid CAS Registry Number.
