Check Digit Verification of cas no

The CAS Registry Mumber 140928-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,9,2 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 140928-19:
(8*1)+(7*4)+(6*0)+(5*9)+(4*2)+(3*8)+(2*1)+(1*9)=124
124 % 10 = 4
So 140928-19-4 is a valid CAS Registry Number.

Dual-Action Penems and Carbapenems

Corraz, Alfred J.,Dax, Scott L.,Dunlap, Norma K.,Georgopapadakou, Nafsika H.,Keith, Dennis D.,et al.

, p. 1828 - 1839 (2007/10/02)

Two series of dual-action antibacterial agents were synthesized in which penems and carbapenems were linked at the 2'-position to quinolones through either an ester or a carbamate moiety.Potent, broad-spectrum antibacterial activity was observed for both
