Benzenemethanesulfenamide, N-[bis(4-methylphenyl)methylene]-, also known as N-(4-methylbenzylidene)-4-methylbenzenesulfenamide, is an organic compound with the chemical formula C16H16N2S. It is a derivative of benzenemethanesulfenamide, featuring two 4-methylphenyl groups attached to the central carbon atom through a methylene bridge. Benzenemethanesulfenamide, N-[bis(4-methylphenyl)methylene]- is characterized by its yellow crystalline appearance and is primarily used as a vulcanization accelerator in the rubber industry, enhancing the strength and elasticity of rubber products. It is also known for its ability to improve the resistance of rubber to heat, oxygen, and aging, making it a valuable additive in various rubber applications.
The CAS Registry Mumber 67157-22-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,1,5 and 7 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 67157-22: (7*6)+(6*7)+(5*1)+(4*5)+(3*7)+(2*2)+(1*2)=136 136 % 10 = 6 So 67157-22-6 is a valid CAS Registry Number.
