Phosphine oxide, diethyloctadecyl-, also known as 1,1-diethyl-2-octadecylphosphine oxide or DEOPO, is a chemical compound with the molecular formula C24H51OP. It is a colorless to pale yellow liquid at room temperature and is soluble in organic solvents. DEOPO is primarily used as a flame retardant and plasticizer in various polymers, such as polyvinyl chloride (PVC) and polyurethane. It functions by reducing the flammability of these materials and improving their thermal stability. Additionally, DEOPO exhibits low toxicity and has a low environmental impact, making it a preferred choice in many applications.

4445-70-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4445-70-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,4 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4445-70:
(6*4)+(5*4)+(4*4)+(3*5)+(2*7)+(1*0)=89
89 % 10 = 9
So 4445-70-9 is a valid CAS Registry Number.
