738-88-5 Usage
General Description
2,2'-oxybis[5-ethyl-5-methyl-1,3,2-dioxaphosphorinane] 2,2'-dioxide, also known as "DEDP," is a chemical compound commonly used as a flame retardant in various materials, including plastics, textiles, and foams. It is an organophosphorus compound that works by inhibiting the spread of flames, making it a valuable additive for products requiring fire resistance. DEDP is a colorless, odorless liquid with low volatility, and it is known for its high thermal stability and resistance to hydrolysis. However, its use has been scaled back in recent years due to concerns about its potential environmental and health risks, particularly its persistence and bioaccumulation in the environment. Despite this, DEDP continues to be used in some specific applications where its fire-retardant properties are essential.
Check Digit Verification of cas no
The CAS Registry Mumber 738-88-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 738-88:
(5*7)+(4*3)+(3*8)+(2*8)+(1*8)=95
95 % 10 = 5
So 738-88-5 is a valid CAS Registry Number.
