6β-[2-(2-fluoro-phenyl)-acetylamino]-penicillanic acid is a semi-synthetic penicillin derivative, which is a type of β-lactam antibiotic. It is structurally similar to penicillanic acid, a key component of many penicillin antibiotics, but with a specific modification. The molecule features a 2-fluoro-phenyl-acetylamino group attached to the 6β position, which enhances its antibacterial properties. This chemical is known for its broad-spectrum activity against various Gram-positive and some Gram-negative bacteria, making it useful in the treatment of a range of bacterial infections. The fluorine atom in the molecule contributes to its increased potency and resistance to bacterial enzymes that can break down other penicillins, thus extending its effectiveness in medical treatments.
The CAS Registry Mumber 391-84-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,9 and 1 respectively; the second part has 2 digits, 8 and 4 respectively. Calculate Digit Verification of CAS Registry Number 391-84: (5*3)+(4*9)+(3*1)+(2*8)+(1*4)=74 74 % 10 = 4 So 391-84-4 is a valid CAS Registry Number.
