Tolylene-2,4-dicarbamic acid chloride, also known as toluene-2,4-diisocyanate (TDI), is an organic compound with the chemical formula C9H6Cl2N2O2. It is a colorless to pale yellow liquid that is widely used in the production of polyurethane foams, elastomers, and coatings. TDI is synthesized by reacting toluene-2,4-diamine with phosgene, resulting in the formation of the dicarbamic acid chloride. Tolylene-2,4-dicarbamic acid chloride is highly reactive and can be hazardous due to its potential to cause respiratory and skin irritation, as well as its classification as a carcinogen. It is essential to handle TDI with proper safety measures and personal protective equipment to minimize health risks.

Check Digit Verification of cas no

The CAS Registry Mumber 2234-27-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,3 and 4 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2234-27:
(6*2)+(5*2)+(4*3)+(3*4)+(2*2)+(1*7)=57
57 % 10 = 7
So 2234-27-7 is a valid CAS Registry Number.
