Hetacillin methyl ester is a semi-synthetic antibiotic derived from the penicillin class, specifically a derivative of ampicillin. It is characterized by its ability to resist destruction by beta-lactamase enzymes, which are produced by some bacteria to evade the effects of penicillins. This resistance makes hetacillin methyl ester effective against a broader range of bacteria compared to standard penicillins. The ester is designed to be hydrolyzed in the body to release the active drug, hetacillin, which then inhibits bacterial cell wall synthesis, leading to bacterial cell lysis and death. Hetacillin methyl ester is used to treat various bacterial infections, including respiratory, urinary tract, and skin infections, as well as certain sexually transmitted diseases. Its effectiveness is contingent upon the susceptibility of the infecting bacteria to the antibiotic.

Check Digit Verification of cas no

The CAS Registry Mumber 4052-65-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,5 and 2 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4052-65:
(6*4)+(5*0)+(4*5)+(3*2)+(2*6)+(1*5)=67
67 % 10 = 7
So 4052-65-7 is a valid CAS Registry Number.
