Toluene diisocyanate dimer (TDI) is a chemical compound derived from the reaction of toluene diisocyanate (TDI) monomers. It is an important industrial chemical used primarily in the production of polyurethane foams, coatings, elastomers, and adhesives. TDI is known for its high reactivity and ability to form strong, durable polymers. However, it is also a hazardous substance, classified as a respiratory and skin sensitizer, which can cause severe health issues if not handled properly. Due to its potential health risks, strict safety measures and regulations are in place for its production, storage, and use.

Check Digit Verification of cas no

The CAS Registry Mumber 9019-84-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,1 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 9019-84:
(6*9)+(5*0)+(4*1)+(3*9)+(2*8)+(1*4)=105
105 % 10 = 5
So 9019-84-5 is a valid CAS Registry Number.
