α,α',β,β'-Tetrachlordiethyl-terephthalat, also known as Tetrachloro-S-Tetrachlorethane or TCT, is a chemical compound with the formula C10H4Cl8O4. It is a white crystalline solid that is insoluble in water but soluble in organic solvents. TCT is primarily used as a flame retardant in various applications, including plastics, textiles, and coatings. It is known for its high thermal stability and resistance to degradation, which makes it effective in preventing the spread of fire. However, due to its potential environmental and health concerns, its use has been restricted or banned in some regions. TCT is also recognized for its persistence in the environment and its ability to accumulate in living organisms, leading to concerns about its long-term impact on ecosystems and human health.
The CAS Registry Mumber 16210-27-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,1 and 0 respectively; the second part has 2 digits, 2 and 7 respectively. Calculate Digit Verification of CAS Registry Number 16210-27: (7*1)+(6*6)+(5*2)+(4*1)+(3*0)+(2*2)+(1*7)=68 68 % 10 = 8 So 16210-27-8 is a valid CAS Registry Number.
