1,3-Bis(4-thiocarbamoyl-phenoxy)-propan, also known as 1,3-bis(4-isothiocyanatophenoxy)propane or BIT, is an organic compound with the chemical formula C15H12N2O2S2. It is a colorless to pale yellow crystalline solid that is soluble in organic solvents. BIT is primarily used as a vulcanizing agent in the rubber industry, particularly for natural rubber and styrene-butadiene rubber, to improve the rubber's strength, elasticity, and resistance to heat, aging, and chemicals. It is also used in the production of adhesives and coatings. Due to its potential health risks, including skin and respiratory irritation, BIT is classified as a hazardous substance and requires proper handling and disposal.

Check Digit Verification of cas no

The CAS Registry Mumber 1238-21-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,3 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1238-21:
(6*1)+(5*2)+(4*3)+(3*8)+(2*2)+(1*1)=57
57 % 10 = 7
So 1238-21-7 is a valid CAS Registry Number.
