[1,1-Difluoro-2-hydroxy-2-(4-methoxy-phenyl)-propyl]-phosphonic acid diethyl ester is a complex organic compound with the chemical formula C11H18F2O5P. It is a derivative of phosphonic acid, featuring a difluorinated hydroxypropyl group and a 4-methoxyphenyl moiety. [1,1-Difluoro-2-hydroxy-2-(4-methoxy-phenyl)-propyl]-phosphonic acid diethyl ester is characterized by its unique structure, which includes a phosphonic acid backbone with two fluorine atoms attached to the carbon adjacent to the hydroxyl group, and a methoxy group on the phenyl ring. It is an ester due to the presence of two ethoxy groups attached to the phosphorus atom. This chemical is of interest in the field of organic chemistry, potentially for its reactivity or as a building block in the synthesis of more complex molecules. Its specific applications and properties would depend on the context in which it is used, such as in pharmaceuticals, materials science, or as a reagent in chemical reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 83567-79-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,6 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 83567-79:
(7*8)+(6*3)+(5*5)+(4*6)+(3*7)+(2*7)+(1*9)=167
167 % 10 = 7
So 83567-79-7 is a valid CAS Registry Number.
