Check Digit Verification of cas no

The CAS Registry Mumber 1242469-32-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,4,6 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1242469-32:
(9*1)+(8*2)+(7*4)+(6*2)+(5*4)+(4*6)+(3*9)+(2*3)+(1*2)=144
144 % 10 = 4
So 1242469-32-4 is a valid CAS Registry Number.

Dual-signaling fluorescent chemosensor based on bisthiazole derivatives

Helal, Aasif,Lee, Sang Hoon,Kim, Sung Hong,Kim, Hong-Seok

, p. 3531 - 3535 (2010)

A new bisthiazole chemosensor (3) with phenolic substituents at the position 2 of the thiazole rings was prepared. The chemosensor 3 acts as a potential dual-function fluorescence chemosensor with Cu2+ and Zn2+ ions causing complete quenching and ratiometric change of fluorescence, respectively. The mechanism of fluorescence was based on the cation-induced inhibition of excited-state intramolecular proton transfer (ESIPT).
