Phosphorous acid, triethenyl ester, also known as triethyl phosphite, is an organic compound with the chemical formula C6H15O3P. It is a colorless, viscous liquid that is soluble in water and has a slight, characteristic odor. This ester is formed by the reaction of phosphorous acid with ethylene oxide and is widely used as a stabilizer for halogenated hydrocarbons, a flame retardant, and a plasticizer. Additionally, it serves as an intermediate in the synthesis of various organophosphorus compounds and is employed in the production of lubricants, pesticides, and other chemicals. Triethyl phosphite is also known for its ability to inhibit corrosion in metalworking fluids and its use as a fuel additive.

3989-17-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3989-17-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,8 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3989-17:
(6*3)+(5*9)+(4*8)+(3*9)+(2*1)+(1*7)=131
131 % 10 = 1
So 3989-17-1 is a valid CAS Registry Number.
