1433373-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1433373-23-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,3,3,7 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1433373-23:
(9*1)+(8*4)+(7*3)+(6*3)+(5*3)+(4*7)+(3*3)+(2*2)+(1*3)=139
139 % 10 = 9
So 1433373-23-9 is a valid CAS Registry Number.

Fluorescence sensing of Cu(II) based on trisphaeridine derivatives
Caballero, Alegría,Campos, Pedro J.,Rodríguez, Miguel A.
, p. 4631 - 4635 (2013/06/26)
The design, synthesis, and ion-sensing properties of new 7,11-diaryltrisphaeridines are described. 2-Thiophenyl and 2-furanyl derivatives behave as highly selective fluorescence chemosensors for Cu2+ cations, with limits of detection (LOD) of 3
