Check Digit Verification of cas no

The CAS Registry Mumber 1421059-64-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,0,5 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1421059-64:
(9*1)+(8*4)+(7*2)+(6*1)+(5*0)+(4*5)+(3*9)+(2*6)+(1*4)=124
124 % 10 = 4
So 1421059-64-4 is a valid CAS Registry Number.

A chemodosimetric probe based on a conjugated oxidized bis-indolyl system for selective naked-eye sensing of cyanide ions in water

Kumari, Namita,Jha, Satadru,Bhattacharya, Santanu

, p. 2805 - 2812 (2012)

A new bis-indolyl-based colorimetric probe has been synthesized. This allows a Michael-type adduct formation for the detection of cyanide ions. The probe shows a remarkable color change from red to colorless upon addition of the cyanide ions in pure water
