6β-((Ξ)-5-amino-2-phenyl-pentanoylamino)-penicillanic acid is a complex chemical compound that serves as a key component in the synthesis of certain semi-synthetic penicillin antibiotics. 6β-((Ξ)-5-amino-2-phenyl-pentanoylamino)-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, (Ξ)-5-amino-2-phenyl-pentanoyl, to the 6β position. This side chain alteration is crucial for enhancing the antibiotic's properties, such as its resistance to bacterial enzymes like penicillinase, which can inactivate natural penicillins. The resulting semi-synthetic penicillins are more stable and effective against a broader range of bacteria, making them valuable in the treatment of various infections.
The CAS Registry Mumber 7601-72-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,0 and 1 respectively; the second part has 2 digits, 7 and 2 respectively. Calculate Digit Verification of CAS Registry Number 7601-72: (6*7)+(5*6)+(4*0)+(3*1)+(2*7)+(1*2)=91 91 % 10 = 1 So 7601-72-1 is a valid CAS Registry Number.
