1253288-74-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1253288-74-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,2,8 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1253288-74:
(9*1)+(8*2)+(7*5)+(6*3)+(5*2)+(4*8)+(3*8)+(2*7)+(1*4)=162
162 % 10 = 2
So 1253288-74-2 is a valid CAS Registry Number.

New highly selective colorimetric and fluorescent chemodosimeters for mercury ion

Wu, Chen-Yu,Lin, Chiung-Cheng,Fu, Tung-Ming,Yang, Chi-Rei,Yen, Yao-Pin

experimental part, p. 329 - 335 (2011/06/19)

Three new chemodosimeters 1-3 were prepared, and their chromogenic and fluorogenic behaviours toward various metal cations were investigated. Receptors 1-3 show an exclusive response toward Hg2+ and also distinguish Hg2+ from other metal cations by different colour changes in aqueous DMSO solution. Among them, receptor 1 also exhibits a pronounced Hg 2+-induced fluorescence enhancement. Therefore, the receptor 1 can be used as a colorimetric and fluorescent chemodosimeter for the determination of Hg2+ion. CSIRO 2010.
