Zinc diphenyldithiophosphate (ZDDP) is a widely used organophosphorus compound, primarily as an antiwear and antioxidant additive in various lubricants, including engine oils, gear oils, and hydraulic fluids. It is known for its ability to form a protective film on metal surfaces, reducing wear and tear, and for its effectiveness in preventing oxidation and corrosion. ZDDP is also recognized for its thermal stability and resistance to high temperatures, making it suitable for use in a range of industrial and automotive applications. However, it is important to note that ZDDP has been associated with certain environmental and health concerns, leading to a gradual shift towards more eco-friendly alternatives in some applications.
The CAS Registry Mumber 20260-60-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,6 and 0 respectively; the second part has 2 digits, 6 and 0 respectively. Calculate Digit Verification of CAS Registry Number 20260-60: (7*2)+(6*0)+(5*2)+(4*6)+(3*0)+(2*6)+(1*0)=60 60 % 10 = 0 So 20260-60-0 is a valid CAS Registry Number.
