3,3,3-Trifluor-1,1,2,2-tetrachlor-1-phenyl-propan, also known as 3,3,3-trifluoro-1,1,2,2-tetrachloropropane or TFTCP, is a halogenated organic compound with the chemical formula C9H4Cl4F3. It is a colorless liquid with a molecular weight of 331.9 g/mol. TFTCP is a persistent organic pollutant (POP) and has been identified as a potential environmental contaminant due to its chemical stability, bioaccumulation, and toxicity. It has been used as a fire retardant, insecticide, and chemical intermediate in various industrial applications. However, due to its harmful effects on human health and the environment, its production and use have been restricted or banned in many countries.
The CAS Registry Mumber 718-65-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,1 and 8 respectively; the second part has 2 digits, 6 and 5 respectively. Calculate Digit Verification of CAS Registry Number 718-65: (5*7)+(4*1)+(3*8)+(2*6)+(1*5)=80 80 % 10 = 0 So 718-65-0 is a valid CAS Registry Number.
