Check Digit Verification of cas no

The CAS Registry Mumber 144339-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,3,3 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144339-13:
(8*1)+(7*4)+(6*4)+(5*3)+(4*3)+(3*9)+(2*1)+(1*3)=119
119 % 10 = 9
So 144339-13-9 is a valid CAS Registry Number.

Compositional Variation of Ionizable Crown Ether-Alkali Metal Ion Complexes in the Solvent Extraction Using Several Extraction Solvents

Sakamoto, Hidefumi,Goto, Hiroki,Doi, Kunio,Otomo, Makoto

, p. 1535 - 1538 (2007/10/02)

Novel benzo-15-crown-5 and 18-crown-6 derivatives bearing an ionizable hydrazone group were synthesized and complex formation equilibria of the compounds with alkali metal ions in solvent extraction were evaluated spectrophotometrically.Formation of 2:2 complexes of the crown ethers with metal ions was observed using chloroform as an extraction solvent.
