1122400-40-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1122400-40-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,2,4,0 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1122400-40:
(9*1)+(8*1)+(7*2)+(6*2)+(5*4)+(4*0)+(3*0)+(2*4)+(1*0)=71
71 % 10 = 1
So 1122400-40-1 is a valid CAS Registry Number.

Visible and near-infrared chemosensor for colorimetric and ratiometric detection of cyanide

Qian, Gang,Li, Xianzhen,Wang, Zhi Yuan

experimental part, p. 522 - 530 (2010/03/24)

A chemosensor system has been developed for rapid and selective detection of cyanide. The sensory molecules have the donor-acceptor type of structure and are designed by tuning the LUMO level or their reactivity towards cyanide. This sensory system is able to selectively distinguish cyanide among fluoride and many other anions at micromolar concentrations and instantly detect cyanide at ambient temperatures with a detection limit down to 1.0 M. Multiple sensory signals are available and can be used for both qualitative monitoring and quantitative determination of cyanide, including high-contrast visual color change, fluorescence quenching and enhancement in the visible and near-infrared spectral regions.
