Check Digit Verification of cas no

The CAS Registry Mumber 1426835-58-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,6,8,3 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1426835-58:
(9*1)+(8*4)+(7*2)+(6*6)+(5*8)+(4*3)+(3*5)+(2*5)+(1*8)=176
176 % 10 = 6
So 1426835-58-6 is a valid CAS Registry Number.

Fluorescent dyad for cooperative recognition of copper cation and halogen anion

Yu, Yanhua,Bogliotti, Nicolas,Maisonneuve, Stéphane,Tang, Jie,Xie, Juan

, p. 1877 - 1883 (2013/04/24)

TMS-ethynyl triazolyl benzothiadiazole (BTD) derivatives have been successfully synthesized by mono deprotection of di-TMS-ethynyl BTD followed by click chemistry. The fluorescence intensity of TMS-ethynyl triazolyl BTD-DCM dyad 8, as well as triazolyl BTD 3, and the DCM derivative 7 could be selectively quenched by Cu2+, but almost not affected by different tested anions. Interestingly, the fluorescence emission of DCM-based fluorophores 7 and 8 was highly sensitive to a combination of Cu2+, F-, or Br- in a sequence dependent manner. With the dyad 8, the detection limit as low as 0.13 ppb could be attained for F- in MeCN. The Cu2+-promoted aerobic oxidative dimerization of DCM moiety to tetrahydrofuran derivatives has also been demonstrated for the first time.
