869-56-7

Tripropyl phosphorotrithioite, also known as TPPT, is an organophosphorus compound with the chemical formula C9H21PS3. It is a colorless liquid that is soluble in organic solvents and has a pungent odor. TPPT is primarily used as an accelerator in the vulcanization of rubber, particularly in the production of tires, hoses, and other rubber goods. It is known for its ability to improve the processing properties of rubber and enhance the mechanical strength of the final product. The compound is also used in the production of some pesticides and as a flame retardant. Due to its potential health and environmental risks, proper handling and disposal procedures are essential when working with TPPT.

869-56-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 869-56-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,6 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 869-56:
(5*8)+(4*6)+(3*9)+(2*5)+(1*6)=107
107 % 10 = 7
So 869-56-7 is a valid CAS Registry Number.
