Check Digit Verification of cas no

The CAS Registry Mumber 1218934-50-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,8,9,3 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1218934-50:
(9*1)+(8*2)+(7*1)+(6*8)+(5*9)+(4*3)+(3*4)+(2*5)+(1*0)=159
159 % 10 = 9
So 1218934-50-9 is a valid CAS Registry Number.

Fluorescent Zn2+ chemosensors, functional in aqueous solution under environmentally relevant conditions

Lee, Amanda E.,Grace, Michael R.,Meyer, Adam G.,Tuck, Kellie L.

, p. 1161 - 1165 (2010)

The synthesis and evaluation of two new ratiometric chemosensors for the quantification of potentially toxic free Zn2+ ions in aqueous solutions are described. Both sensors show high selectivity for Zn2+ over other cations, and are functional at environmentally relevant pH with detection limits of 0.05 μM for free Zn2+.
