Phosphorodiisocyanatidous fluoride, also known as difluorophosphoric acid diisocyanide or PF3(N=C=O)2, is a chemical compound with the molecular formula C2F2N2OP. It is a colorless, volatile, and highly toxic liquid that is sensitive to moisture and heat. Phosphorodiisocyanatidous fluoride (7CI,8CI,9CI) is an important intermediate in the synthesis of various phosphorus-containing compounds and is used in the production of pesticides, flame retardants, and other industrial chemicals. Due to its reactivity and toxicity, it requires careful handling and storage to prevent exposure and environmental contamination.

Check Digit Verification of cas no

The CAS Registry Mumber 459-77-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,5 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 459-77:
(5*4)+(4*5)+(3*9)+(2*7)+(1*7)=88
88 % 10 = 8
So 459-77-8 is a valid CAS Registry Number.
