Benzenepropanoic acid, α-fluoro-β-oxo-α-(phenylsulfonyl)-, ethyl ester is a complex organic compound with the chemical formula C16H13FO4S. It is a derivative of benzenepropanoic acid, featuring a fluorine atom at the α-position, an oxo group at the β-position, and a phenylsulfonyl group attached to the α-position. The ethyl ester functional group is present, indicating that the carboxylic acid group is esterified with ethanol. Benzenepropanoic acid, a-fluoro-b-oxo-a-(phenylsulfonyl)-, ethyl ester is known for its potential applications in pharmaceuticals, particularly as an intermediate in the synthesis of certain drugs. It is characterized by its unique structure, which combines the properties of benzene, propanoic acid, and the phenylsulfonyl group, making it a versatile building block in organic chemistry.
The CAS Registry Mumber 139101-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,0 and 1 respectively; the second part has 2 digits, 2 and 8 respectively. Calculate Digit Verification of CAS Registry Number 139101-28: (8*1)+(7*3)+(6*9)+(5*1)+(4*0)+(3*1)+(2*2)+(1*8)=103 103 % 10 = 3 So 139101-28-3 is a valid CAS Registry Number.
