Check Digit Verification of cas no

The CAS Registry Mumber 857503-95-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,5,0 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 857503-95:
(8*8)+(7*5)+(6*7)+(5*5)+(4*0)+(3*3)+(2*9)+(1*5)=198
198 % 10 = 8
So 857503-95-8 is a valid CAS Registry Number.

Rajakumar, Perumal,Sekar, Karuppannan,Shanmugaiah, Vellasamy,Mathivanan, Narayanasamy

, p. 4416 - 4419 (2008)

Synthesis of fluorescent imidazole-based dicationic carbazolophanes incorporating various spacer units is described. Interestingly, the cyclophanes 2a and 5a incorporating a pyridine moiety exhibited superior antibacterial activity against most of the pathogenic bacteria in the tested concentrations as compared to the other cyclophanes as well as the test control, benzalkonium chloride (BAC), cetylpyridinium chloride (CPC) and tetracycline.
