Trimethyl phosphono acetate, also known as tri-o-cresyl phosphate (TOCP), is an organophosphorus compound with the chemical formula C9H13O4P. It is a colorless, oily liquid that is soluble in organic solvents and has a slight odor. This chemical is primarily used as a plasticizer, flame retardant, and pesticide, and it is also found in some lubricating oils. However, it is important to note that TOCP is a potent neurotoxin and has been associated with severe health issues, including paralysis and death, when ingested in large quantities. Due to its toxicity, the use of TOCP has been restricted or banned in many countries.
The CAS Registry Mumber 19926-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,2 and 6 respectively; the second part has 2 digits, 6 and 8 respectively. Calculate Digit Verification of CAS Registry Number 19926-68: (7*1)+(6*9)+(5*9)+(4*2)+(3*6)+(2*6)+(1*8)=152 152 % 10 = 2 So 19926-68-2 is a valid CAS Registry Number.
