Diisocyanato-phenyl-phosphine, also known as bis(4-isocyanatophenyl)phenylphosphine, is an organophosphorus compound with the chemical formula C18H12N2OP. It is a white crystalline solid that is sensitive to moisture and air. diisocyanato-phenyl-phosphine is primarily used as a precursor in the synthesis of various phosphorus-containing materials, such as flame retardants, pesticides, and pharmaceuticals. Due to its reactivity, diisocyanato-phenyl-phosphine is typically handled under an inert atmosphere to prevent unwanted side reactions. Its unique structure, featuring a phosphorus atom bonded to two isocyanato groups and a phenyl group, makes it a valuable building block in the development of new materials with specific properties.

Check Digit Verification of cas no

The CAS Registry Mumber 2736-49-4 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 9 respectively.
Calculate Digit Verification of CAS Registry Number 2736-49:
(6*2)+(5*7)+(4*3)+(3*6)+(2*4)+(1*9)=94
94 % 10 = 4
So 2736-49-4 is a valid CAS Registry Number.
