Check Digit Verification of cas no

The CAS Registry Mumber 40221-64-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,2,2 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 40221-64:
(7*4)+(6*0)+(5*2)+(4*2)+(3*1)+(2*6)+(1*4)=65
65 % 10 = 5
So 40221-64-5 is a valid CAS Registry Number.

Cu(II) complex of an abiotic receptor as highly selective fluorescent sensor for acetate

Goswami, Shyamaprosad,Chakrabarty, Rinku

, p. 5994 - 5997 (2009)

A copper complex having quinoline moiety as fluorophore has been synthesized. The anion recognition behavior of the receptor and its copper complex has been studied in acetonitrile and in acetonitrile: H2O (95:5 v/v). The copper complex shows high selectivity toward acetate over other anions studied such as F-, Cl-, Br-, I-, OAc-, dl-malate, l-mandelate, benzoate, isophthalate, H2 PO4-, NO3- and HSO4-.
