4,4'-Bis-(4-chlor-benzyliden-amino)-diphenyl-disulfid, also known as 4,4'-Bis(4-chlorobenzylideneamino)diphenyl disulfide, is a chemical compound with the molecular formula C28H20Cl2N2S2. It is a white to off-white crystalline solid that is soluble in organic solvents. 4,4'-Bis-(4-chlor-benzyliden-amino)-diphenyl-disulfid is primarily used as an accelerator in the vulcanization process of rubber, particularly for natural rubber and styrene-butadiene rubber. It enhances the rate of硫化反应, improving the rubber's strength, elasticity, and resistance to wear. Due to its chemical structure, it is also known for its thermal stability and resistance to aging, making it a valuable additive in the rubber industry.
The CAS Registry Mumber 3430-51-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,3 and 0 respectively; the second part has 2 digits, 5 and 1 respectively. Calculate Digit Verification of CAS Registry Number 3430-51: (6*3)+(5*4)+(4*3)+(3*0)+(2*5)+(1*1)=61 61 % 10 = 1 So 3430-51-1 is a valid CAS Registry Number.
