6β-((Ξ)-4-amino-2-phenyl-butyrylamino)-penicillanic acid is a complex chemical compound that serves as a key component in the synthesis of certain semi-synthetic penicillin antibiotics. 6β-((Ξ)-4-amino-2-phenyl-butyrylamino)-penicillanic acid is derived from the penicillanic acid nucleus, which is the core structure of penicillin, and is modified by the attachment of a side chain, specifically (Ξ)-4-amino-2-phenyl-butyrylamino. The presence of this side chain alters the antibiotic's properties, such as its spectrum of activity and resistance profile, making it suitable for treating a variety of bacterial infections. The chemical's structure and properties are crucial for its medicinal applications, as they determine its interaction with bacterial cell walls and its ability to inhibit bacterial growth effectively.
The CAS Registry Mumber 7548-77-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,4 and 8 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 7548-77: (6*7)+(5*5)+(4*4)+(3*8)+(2*7)+(1*7)=128 128 % 10 = 8 So 7548-77-8 is a valid CAS Registry Number.
