Check Digit Verification of cas no

The CAS Registry Mumber 1388820-11-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,8,8,2 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1388820-11:
(9*1)+(8*3)+(7*8)+(6*8)+(5*8)+(4*2)+(3*0)+(2*1)+(1*1)=188
188 % 10 = 8
So 1388820-11-8 is a valid CAS Registry Number.

Synthesis of 2-(3-methyl-2-oxoquinoxalin-1(2H)-yl)acetamide-based azetidinone derivatives as potent antibacterial and antifungal agents

Kumar, Shiv,Kumar, Nitin,Drabu, Sushma,Minhaj, Md. Akram

, p. 129 - 139 (2013)

Twelve compounds belonging to series N-[3-chloro-2-oxo-4-(substituted) phenylazetidin-1-yl]-2-(3-methyl-2-oxoquinoxalin-1(2H)-yl)acetamide (5a-l) were synthesized. These compounds were evaluated for their in vitro antibacterial against E. coli, S. aureus, K. pneumoniae, P. aeruginosa and antifungal activity against C. albicans, A. niger and A. flavus by cup-plate method. Structures of all the newly synthesized compounds were confirmed by their spectral data interpretation. Compound 5g having p-dimethylaminophenyl group on 4-position of azetidinone ring attached to N-atom of acetamido group on 1-position of 3-methyl-1H-quinoxaline-2-one, was found to be active against all the bacterial and fungal strains under investigation.
