Meta-phenylenediisocyanate (m-PDI) is an organic compound with the chemical formula C8H4N2O2, characterized by its two isocyanate functional groups attached to a meta-positioned phenyl ring. It is a colorless to pale yellow liquid with a pungent odor and is widely used in the production of polyurethane foams, elastomers, and coatings due to its ability to react with various substrates, such as polyols, to form strong, durable polymers. m-PDI is also known for its potential health risks, as it can cause respiratory and skin irritation, and is classified as a hazardous substance.

935-27-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 935-27-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.Calculate Digit Verification of CAS Registry Number 935-27:
(5*9)+(4*3)+(3*5)+(2*2)+(1*7)=83
83 % 10 = 3
So 935-27-3 is a valid CAS Registry Number.
