"6β-(2-phenyl-acetylamino)-penicillanic acid (Ξ)-1-ethoxy-ethyl ester" is a complex chemical compound, primarily known as a semi-synthetic penicillin derivative. It is characterized by its ability to inhibit bacterial cell wall synthesis, thereby acting as an effective antibiotic. 6β-(2-phenyl-acetylamino)-penicillanic acid (Ξ)-1-ethoxy-ethyl ester is derived from the modification of the natural penicillin structure, specifically by acetylating the 6β-amino group with a 2-phenyl-acetylamino group, which enhances its resistance to certain bacterial enzymes like penicillinase. The ethoxy-ethyl ester group in the compound serves as a pro-drug, which is hydrolyzed in the body to release the active antibiotic. This chemical is used in the treatment of various bacterial infections, particularly those caused by penicillinase-producing bacteria, due to its improved stability and effectiveness.
The CAS Registry Mumber 748-79-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,4 and 8 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 748-79: (5*7)+(4*4)+(3*8)+(2*7)+(1*9)=98 98 % 10 = 8 So 748-79-8 is a valid CAS Registry Number.
