Check Digit Verification of cas no

The CAS Registry Mumber 220327-47-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,3,2 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 220327-47:
(8*2)+(7*2)+(6*0)+(5*3)+(4*2)+(3*7)+(2*4)+(1*7)=89
89 % 10 = 9
So 220327-47-9 is a valid CAS Registry Number.

Synthesis and diuretic activity of 4,5-dihydro-6H-imidazo[4,5,1- ij]quinoline-6-one 6-oxime-O-sulfonic acid derivatives

, p. 763 - 774 (2007/10/03)

Using our previously reported 7-chloro-2,3-dihydro-1-(2-methylbenzoyl)- 4(1H)-quinolinone 4-oxime-O-sulfonic acid potassium salt la (M17055) as a lead, a series of tricyclic (2a-o, 3, 4, 5) and tetracyclic (6) quinolinone oxime O-sulfonic acid derivatives were synthesized by ring annulation of the 1-(2-methylbenzoyl) moiety to the quinolinone skeleton. They were compared with furosemide and compound 1a for diuretic activity in dogs; some tricyclic 4,5-dihydro-6H-imidazo[4,5,1-ij]quinoline-6-one 6-oxime-O-sulfonic acid derivatives showed diuretic activity comparable (2c,e) or superior (2m) to the lead compound 1a. These results are discussed on the basis of a comparison of the conformational and electronic characteristics of the relevant compounds with the aid of computer graphics.
