It is a colorless to pale yellow liquid that is soluble in most organic solvents and has a molecular weight of 334.45 g/mol. phosphonic acid dinonyl ester is primarily used as a plasticizer, flame retardant, and anti-corrosion agent in various industrial applications, including the production of plastics, rubber, and coatings. It is known for its excellent thermal stability, low volatility, and resistance to hydrolysis, which makes it a valuable additive in the manufacturing of materials that require these properties.
The CAS Registry Mumber 5934-99-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,3 and 4 respectively; the second part has 2 digits, 9 and 9 respectively. Calculate Digit Verification of CAS Registry Number 5934-99: (6*5)+(5*9)+(4*3)+(3*4)+(2*9)+(1*9)=126 126 % 10 = 6 So 5934-99-6 is a valid CAS Registry Number.
