Check Digit Verification of cas no

The CAS Registry Mumber 171740-86-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,7,4 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 171740-86:
(8*1)+(7*7)+(6*1)+(5*7)+(4*4)+(3*0)+(2*8)+(1*6)=136
136 % 10 = 6
So 171740-86-6 is a valid CAS Registry Number.

Silver Ion Selective Extraction with Dithiaza-, Tetrathiaza-, and Tetrathiadiazacrown Ether Derivatives

Sakamoto, Hidefumi,Ishikawa, Junichi,Otomo, Makoto

, p. 2831 - 2836 (2007/10/03)

Dithiazacrown, tetrathiazacrown, and two tetrathiadiazacrown ether derivatives, bearing a phenyl group on each nitrogen atom at the periphery, were synthesized, and the solvent extractions of some transition metal ions with these compounds were carried out using an H2O-1,2-dichloroethane system.All of the thiazacrown compounds employed exhibited Ag+ selectivity, and formed 1:1:1 complexes of Ag+ : ligand : laurate ion as a counter anion to be extracted into a 1,2-dichloroethane solution.The extractabilities (extraction constants, Kex) for Ag+ decreased in the order: 7,16-diphenyltetrathia-7,16-diaza-18-crown-6 (3) (log Kex = 1.18+/-0.13) > 13-phenyltetrathia-13-aza-15-crown-5 (2) (0.75+/-0.09) > 7-phenyldithia-7-aza-9-crown-3 (1) (-0.47+/-0.06)>13, 16-diphenyltetrathia-13,16-diaza-18-crwon-6 (4) (-0.62+/-0.16).
