Check Digit Verification of cas no
The CAS Registry Mumber 112732-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,7,3 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 112732-17:
(8*1)+(7*1)+(6*2)+(5*7)+(4*3)+(3*2)+(2*1)+(1*7)=89
89 % 10 = 9
So 112732-17-9 is a valid CAS Registry Number.

Cycloaracylation of Enamines, I. - Synthesis of 4-Quinolone-3-carboxylic Acids
Grohe, Klaus,Heitzer, Helmut
, p. 29 - 37 (2007/10/02)
Starting with o-halobenzoyl chlorides 4 and open-chain secondary enamines 5, a new synthesis of 4-quinolone-3-carboxylic acids 12 is described.The reaction of 7-haloquinolone-3-carboxylic acids 12a-k with aliphatic amines 14 produces highly active antibacterial 7-aminoquinolone-3-carboxylic acids 15.The main product of the 1-cyclopropyl series, "ciprofloxacin" (15a), is being developed as a broad-spectrum chemotherapeutic agent.
