Check Digit Verification of cas no

The CAS Registry Mumber 1622074-14-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,2,0,7 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1622074-14:
(9*1)+(8*6)+(7*2)+(6*2)+(5*0)+(4*7)+(3*4)+(2*1)+(1*4)=129
129 % 10 = 9
So 1622074-14-9 is a valid CAS Registry Number.

Biaryl-based anion receptors bearing thiourea groups: Fluoride anion receptor

Takahashi, Yohei,Endo, Masatoshi,Ito, Kazuaki

, p. 237 - 245 (2014/06/09)

The synthesis, characterization and binding studies with anions for biaryl-based anion receptors bearing thiourea groups have been described. The results revealed that receptors (1 and 2) showed good selectivity and binding affinity for F-, and among them binaphthyl-based receptor (1a) showed the best binding affinity for F-in comparison to other tested anions (Cl-, Br-, I-, NO-3 ; HSO-4 ; AcO-And H2PO-4 ). This is probably due to the fact that the moderate rigidity of binaphthyl skeleton in 1a is able to provide the better geometry of two thiourea groups for incorporating F-into the binding pocket. The higher basicity of F-Also participated in this selectivity. Springer Science+Business Media Dordrecht 2013.
