Phenyl-2-trioxaphosphocane-1,3,6,2, also known as triphenyl phosphate (TPHP), is an organophosphorus compound with the chemical formula C18H15O4P. It is a colorless, crystalline solid that is widely used as a flame retardant and plasticizer in various materials, including plastics, textiles, and rubber. TPHP is known for its thermal stability, low toxicity, and ability to improve the flexibility and durability of polymers. However, due to concerns about its potential endocrine-disrupting properties and environmental persistence, its use has been restricted or banned in some applications and regions.
The CAS Registry Mumber 1079-69-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,7 and 9 respectively; the second part has 2 digits, 6 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1079-69: (6*1)+(5*0)+(4*7)+(3*9)+(2*6)+(1*9)=82 82 % 10 = 2 So 1079-69-2 is a valid CAS Registry Number.
