Dibutyl phenyl phosphorotrithioite, also known as DBPPT, is an organophosphorus compound with the chemical formula C16H25PS3. It is a colorless to pale yellow liquid that is soluble in organic solvents and has a pungent odor. DBPPT is primarily used as a flame retardant and plasticizer in various materials, including plastics, rubber, and adhesives. It functions by releasing phosphorus and sulfur when exposed to heat, which helps to interrupt the combustion process and slow down the spread of fire. Due to its effectiveness and versatility, DBPPT is widely employed in the manufacturing of various products, such as electrical cables, automotive parts, and construction materials. However, concerns have been raised about its potential environmental and health impacts, leading to restrictions on its use in some applications.

Check Digit Verification of cas no

The CAS Registry Mumber 3819-63-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,1 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3819-63:
(6*3)+(5*8)+(4*1)+(3*9)+(2*6)+(1*3)=104
104 % 10 = 4
So 3819-63-4 is a valid CAS Registry Number.
