Isopropylphosphonic acid diisocyanate, also known as IPDI, is an organic compound with the chemical formula C6H9NO3P. It is a colorless to pale yellow liquid that is widely used in the production of polyurethane foams, elastomers, and coatings due to its ability to form strong, flexible, and durable polymers. IPDI is synthesized by reacting isopropylphosphonic acid with phosgene, and it is characterized by its two isocyanate functional groups, which allow it to react with other compounds containing active hydrogen atoms, such as polyols, to form polyurethane polymers. This chemical is known for its high reactivity and is used in various industrial applications, including the production of flexible and rigid foams, adhesives, sealants, and elastomers.

Check Digit Verification of cas no

The CAS Registry Mumber 2736-47-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,3 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2736-47:
(6*2)+(5*7)+(4*3)+(3*6)+(2*4)+(1*7)=92
92 % 10 = 2
So 2736-47-2 is a valid CAS Registry Number.
