Ampicillin is a broad-spectrum beta-lactam antibiotic derived from the bacterium Streptomyces and is commonly used to treat a variety of bacterial infections, such as respiratory, urinary, and gastrointestinal infections. It works by inhibiting bacterial cell wall synthesis, leading to cell lysis and death. Ampicillin is effective against both Gram-positive and some Gram-negative bacteria, but its efficacy can be reduced by the presence of beta-lactamase enzymes produced by some bacteria. It is available in various forms, including oral capsules, injections, and intravenous solutions, and is often prescribed in combination with other antibiotics to enhance its effectiveness or to broaden its spectrum of activity.
The CAS Registry Mumber 3381-68-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,8 and 1 respectively; the second part has 2 digits, 6 and 8 respectively. Calculate Digit Verification of CAS Registry Number 3381-68: (6*3)+(5*3)+(4*8)+(3*1)+(2*6)+(1*8)=88 88 % 10 = 8 So 3381-68-8 is a valid CAS Registry Number.
