Benzene, 1,1'-methylenebis[4-isocyanato-3-methoxy-, also known as Desmodur 44A or TDI, is a chemical compound with the formula C15H10N2O4. It is a white crystalline solid that is widely used in the production of polyurethane foams, elastomers, and coatings. TDI is a diisocyanate, which means it contains two isocyanate functional groups that can react with various substrates to form urethane linkages. Due to its high reactivity and potential health risks, it is important to handle TDI with proper safety precautions, including the use of personal protective equipment and proper ventilation.

Check Digit Verification of cas no
The CAS Registry Mumber 5207-17-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,0 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.Calculate Digit Verification of CAS Registry Number 5207-17:
(6*5)+(5*2)+(4*0)+(3*7)+(2*1)+(1*7)=70
70 % 10 = 0
So 5207-17-0 is a valid CAS Registry Number.
