{(C6H5)2PN}(x) represents a class of organophosphorus compounds, where "C6H5" denotes a phenyl group, "P" stands for phosphorus, and "N" represents nitrogen. These compounds are characterized by the presence of a phosphorus atom bonded to two phenyl groups and a nitrogen atom, with "x" indicating the number of such units in the molecule. They are known for their potential applications in various fields, including as flame retardants, pesticides, and chemical intermediates. The specific properties and reactivity of these compounds can vary depending on the value of "x" and the overall molecular structure, which influences their stability, solubility, and interaction with other chemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 1663-41-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,6 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1663-41:
(6*1)+(5*6)+(4*6)+(3*3)+(2*4)+(1*1)=78
78 % 10 = 8
So 1663-41-8 is a valid CAS Registry Number.
