Check Digit Verification of cas no

The CAS Registry Mumber 1824496-31-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,8,2,4,4,9 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1824496-31:
(9*1)+(8*8)+(7*2)+(6*4)+(5*4)+(4*9)+(3*6)+(2*3)+(1*1)=192
192 % 10 = 2
So 1824496-31-2 is a valid CAS Registry Number.

Synthesis and photophysical properties of new fluorinated benzo[c]xanthene dyes as intracellular pH indicators

Liu, Jixiang,Diwu, Zhenjun,Leung, Wai-Yee

, p. 2903 - 2905 (2007/10/03)

Two new fluorinated benzo[c]xanthene dyes were synthesized by reaction of fluorinated 1,6-dihydroxynaphthalenes with 2,4- (and 2,5)-dicarboxy-3′-dimethylamino-2′-hydroxybenzophenone. The two critical fluorinated 1,6-dihydroxynaphthalene intermediates were prepared via a regioselective route. The fluorinated benzo[c]xanthene dyes exhibit desired lower pKa values (6.4 and 7.2, respectively) than their parent compound (pKa = 7.5) while the pH-dependent dual-emission characteristics are well retained. Their cell-permeable esters have been prepared for intracellular applications.
