54557-81-2 Usage
General Description
4-[3,4-(Ethylendioxy)phenyl]-4-oxobutyric Acid is a complex organic compound that belongs to the category of phenylpropanoids and polyketides. This chemical, like other similar compounds, consists of a phenylpropane backbone, which is often synthesized from the amino acids phenylalanine or tyrosine. Further, it is usually characterized by the presence of an ethylene dioxy group (two oxygen atoms bound to each other) connected to the phenyl ring. The "4-oxobutyric acid" part of its name refers to the presence of a ketone (double-bonded oxygen to a carbon) and a carboxyl (carbon double-bonded to an oxygen and single-bonded to a hydroxyl group) in its structure. Details regarding its specific uses, sources, and preparation aren't widely available, suggesting that it may not be a commonly utilized or synthesized chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 54557-81-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,5,5 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 54557-81:
(7*5)+(6*4)+(5*5)+(4*5)+(3*7)+(2*8)+(1*1)=142
142 % 10 = 2
So 54557-81-2 is a valid CAS Registry Number.

An efficient and general trifluoromethylthiolation of silylenol ethers and β-naphthols have been accomplished employing the combination of diethylaminosulfur trifluoride (DAST) and (trifluoromethyl)trimethylsilane (CF3TMS) as source of electrophilic trifluoromethylthio moiety for the synthesis of α-trifluoromethylthiolated carbonyl compounds and β-naphthols in good yields. Important features of this method include wide functional group tolerance and use of readily available DAST/CF3TMS. Potential of the methodology was demonstrated via the synthesis of α-trifluoromethylthiolated (+)-4-cholesten-3-one and naphthoquinone. (Figure presented.).
