Diethyl (2-oxooctyl)phosphonate, also known as DEOP, is an organophosphorus compound with the chemical formula C12H25O3P. It is a colorless liquid with a molecular weight of 248.31 g/mol. DEOP is primarily used as a flame retardant and plasticizer in various applications, including plastics, rubber, and textiles. It functions by releasing phosphorus-containing compounds when exposed to heat, which can interrupt the combustion process and slow down the spread of fire. The compound is also known for its low toxicity and environmental persistence, making it a preferred choice in certain industries over more hazardous alternatives. However, due to its potential environmental impact, its use is subject to regulatory controls in some regions.

Check Digit Verification of cas no

The CAS Registry Mumber 3452-99-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,5 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3452-99:
(6*3)+(5*4)+(4*5)+(3*2)+(2*9)+(1*9)=91
91 % 10 = 1
So 3452-99-1 is a valid CAS Registry Number.
