Benzenecarbothioic acid, S,S'-methylene ester (9CI), also known as methylene bis(benzenecarbothioate) or MBT, is an organic compound with the chemical formula C15H12S2. It is a colorless to pale yellow crystalline solid that is soluble in most organic solvents. MBT is primarily used as an accelerator in the vulcanization of rubber, particularly in the production of tires, where it enhances the strength and durability of the rubber. It is also used in the manufacturing of adhesives and as a fungicide in agriculture. The compound is known for its effectiveness in promoting the cross-linking of rubber molecules, which results in improved elasticity and resistance to wear. However, due to its potential health and environmental concerns, its use is regulated in some regions.

2242-21-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2242-21-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,4 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2242-21:
(6*2)+(5*2)+(4*4)+(3*2)+(2*2)+(1*1)=49
49 % 10 = 9
So 2242-21-9 is a valid CAS Registry Number.
