1,1,3,3-Tetrachloro-2-phenyl-propene, also known as α-tetrachloroterephthalic acid or TCPP, is a chlorinated organic compound with the chemical formula C10H4Cl4. It is a white crystalline solid that is insoluble in water and has a low vapor pressure. TCPP is primarily used as a flame retardant in various applications, including polyurethane foams, textiles, and plastics. Due to its persistence in the environment and potential health risks, its use has been restricted or banned in several countries. The compound is characterized by its four chlorine atoms attached to the phenyl ring and the propene backbone, which contributes to its flame-retardant properties.
The CAS Registry Mumber 1600-38-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,0 and 0 respectively; the second part has 2 digits, 3 and 8 respectively. Calculate Digit Verification of CAS Registry Number 1600-38: (6*1)+(5*6)+(4*0)+(3*0)+(2*3)+(1*8)=50 50 % 10 = 0 So 1600-38-0 is a valid CAS Registry Number.
