Check Digit Verification of cas no

The CAS Registry Mumber 203127-11-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,1,2 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 203127-11:
(8*2)+(7*0)+(6*3)+(5*1)+(4*2)+(3*7)+(2*1)+(1*1)=71
71 % 10 = 1
So 203127-11-1 is a valid CAS Registry Number.

Ester prodrugs of ampicillin tailored for intracellular accumulation

Fan,Paternotte,Vermander,Li,Beaujean,Scorneaux,Dumont,Osinski,Claesen,Tulkens,Sonveaux

, p. 3107 - 3112 (2007/10/03)

Seven new ester prodrugs of ampicillin with hydrolysis half-lives ranging from 65 to 308 min were synthesized. The cellular accumulation of two of them (in J774 mouse macrophages) and their activities against intracellular Staphylococcus aureus were determined in comparison with the pivaloyloxymethylester of ampicillin (pivampicillin) and ampicillin. The esters accumulated extensively and were more active than ampicillin in this in vitro system.
