6β-Aminopenicillanic acid S-oxide (6-APA S-oxide) is a chemical derivative of 6-aminopenicillanic acid (6-APA), which is a key intermediate in the synthesis of semi-synthetic penicillins. The S-oxide form is characterized by the presence of an oxygen atom bonded to the sulfur atom in the side chain, which can influence its reactivity and properties. This modification can potentially enhance the stability or bioavailability of the molecule, making it a subject of interest in pharmaceutical research for the development of new antibiotics. The S-oxide derivative may also exhibit different biological activities compared to the parent compound, 6-APA, due to the altered electronic environment around the sulfur atom.

Check Digit Verification of cas no

The CAS Registry Mumber 4888-97-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,8 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4888-97:
(6*4)+(5*8)+(4*8)+(3*8)+(2*9)+(1*7)=145
145 % 10 = 5
So 4888-97-5 is a valid CAS Registry Number.
