Butanedioic acid, (2-oxo-2-phenylethyl)(triphenylphosphoranylidene)-, dimethyl ester is a complex organic compound with the chemical formula C30H27O4P. It is a derivative of butanedioic acid, featuring a 2-oxo-2-phenylethyl group and a triphenylphosphoranylidene moiety. The dimethyl ester form indicates that the two carboxylic acid groups of butanedioic acid are esterified with methanol, resulting in a molecule with a phosphorus atom double-bonded to the carbonyl carbon of the 2-oxo-2-phenylethyl group. Butanedioic acid, (2-oxo-2-phenylethyl)(triphenylphosphoranylidene)-, dimethyl ester is likely to be used in organic synthesis, particularly in the formation of complex molecules or as a reagent in various chemical reactions. Its structure provides a unique combination of acidic, ester, and phosphorus-containing functional groups, which can be exploited in the design of new pharmaceuticals, agrochemicals, or materials.

Check Digit Verification of cas no

The CAS Registry Mumber 3448-47-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,4 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3448-47:
(6*3)+(5*4)+(4*4)+(3*8)+(2*4)+(1*7)=93
93 % 10 = 3
So 3448-47-3 is a valid CAS Registry Number.
