Check Digit Verification of cas no

The CAS Registry Mumber 182868-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,8,6 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 182868-20:
(8*1)+(7*8)+(6*2)+(5*8)+(4*6)+(3*8)+(2*2)+(1*0)=168
168 % 10 = 8
So 182868-20-8 is a valid CAS Registry Number.

The synthesis and in vitro antibacterial activity of conformationally restricted quinolone antibacterial agents

Cooper, Curt S.,Tufano, Michael D.,Donner, Pamela K.,Chu, Daniel T. W.

, p. 1307 - 1315 (2007/10/03)

Two series of conformationally restricted quinolone antibacterials were synthesized. One series was restricted by formation of a tetrahydrofuran ring between the C-6 position and the C-7 position of the quinolone ring skeleton. The second series achieved conformational rigidity by formation of a tetrahydrofuran ring between the C-7 and the C-8 positions. These compounds were evaluated for their in vitro antibacterial activity. Compounds 19 and 20 were the most active compounds in either series and were about equipotent.
