p-Menthane-1,8-diyl diisocyanate, also known as menthane diisocyanate or MDI, is a chemical compound with the formula C16H22N2O2. It is a colorless to pale yellow liquid with a strong, pungent odor. MDI is a diisocyanate, which means it contains two isocyanate functional groups (-NCO) that can react with various substrates to form polyurethane polymers. It is widely used in the production of polyurethane foams, elastomers, and coatings due to its excellent properties such as high strength, flexibility, and durability. MDI is also known for its low toxicity and environmental friendliness compared to other diisocyanates like toluene diisocyanate (TDI). However, it is still considered a hazardous substance and requires proper handling and safety measures during its use.

5116-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5116-72-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,1 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.Calculate Digit Verification of CAS Registry Number 5116-72:
(6*5)+(5*1)+(4*1)+(3*6)+(2*7)+(1*2)=73
73 % 10 = 3
So 5116-72-3 is a valid CAS Registry Number.
