Bis(diethyldithiophosphinato)zinc, also known as zinc diethyldithiophosphate (ZDDP), is a chemical compound with the formula Zn[S2P(OEt)2]2. It is a widely used antiwear and antioxidant additive in various lubricants, including engine oils, gear oils, and hydraulic fluids. ZDDP works by forming a protective film on metal surfaces, reducing wear and preventing metal-to-metal contact. It also helps to neutralize acidic byproducts formed during the oxidation of the lubricant, thus extending the life of the oil and protecting the machinery from corrosion. The compound is known for its effectiveness in extreme temperature conditions and under heavy load, making it a valuable component in the formulation of high-performance lubricants.

Check Digit Verification of cas no

The CAS Registry Mumber 2512-59-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,1 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2512-59:
(6*2)+(5*5)+(4*1)+(3*2)+(2*5)+(1*9)=66
66 % 10 = 6
So 2512-59-6 is a valid CAS Registry Number.
