Check Digit Verification of cas no

The CAS Registry Mumber 1428133-84-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,1,3 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1428133-84:
(9*1)+(8*4)+(7*2)+(6*8)+(5*1)+(4*3)+(3*3)+(2*8)+(1*4)=149
149 % 10 = 9
So 1428133-84-9 is a valid CAS Registry Number.

Colorimetric and fluorescent detection of biological thiols in aqueous solution

Li, Yin-Hui,Yang, Jin-Feng,Liu, Chang-Hui,Li, Ji-Shan,Yang, Rong-Hua

, p. 96 - 98 (2013)

A new colorimetric and fluorescent probe, 2-(2,4-dinitrostyryl)-1,3,3- trimethyl-3H-indolium iodide (DTI), for selective and sensitive detection of biological thiols is reported. In aqueous solution at physiological pH 7.4, biological thiols react with DTI via Michael addition to give the brownish red adduct concomitant with fluorescence emission decrease.
