6β-(2-phenyl-acetylamino)-penicillanic acid ethoxymethyl ester is a semi-synthetic penicillin derivative, which is a type of β-lactam antibiotic. It is structurally similar to penicillin, with a phenyl-acetylamino group attached to the 6β position of the penicillanic acid nucleus. This modification enhances the antibiotic's ability to resist enzymatic degradation by penicillinases, which are enzymes produced by some bacteria to inactivate penicillin. The ethoxymethyl ester group is a protecting group that can be removed in the body to release the active drug. 6β-(2-phenyl-acetylamino)-penicillanic acid ethoxymethyl ester is used to treat a variety of bacterial infections, particularly those caused by penicillinase-producing bacteria, due to its resistance to these enzymes. It is an important component in the arsenal of antibiotics used to combat resistant strains of bacteria.

Check Digit Verification of cas no

The CAS Registry Mumber 909-66-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,0 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 909-66:
(5*9)+(4*0)+(3*9)+(2*6)+(1*6)=90
90 % 10 = 0
So 909-66-0 is a valid CAS Registry Number.
