Check Digit Verification of cas no

The CAS Registry Mumber 147951-24-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,9,5 and 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 147951-24:
(8*1)+(7*4)+(6*7)+(5*9)+(4*5)+(3*1)+(2*2)+(1*4)=154
154 % 10 = 4
So 147951-24-4 is a valid CAS Registry Number.

Imidazole-based dithienylethenes as a selective chemosensors for iron(III) ions

Huang, Shuyuan,Li, Ziyong,Li, Sisi,Yin, Jun,Liu, Shenghua

scheme or table, p. 961 - 966 (2012/04/04)

Four novel imidazole-based dithienylethenes have been successfully synthesized in good yields. Their structures have been confirmed by NMR spectrometry, mass spectrometry, and elemental analyses. UV/Vis absorption spectra indicated that these dithienylethenes can easily isomerize between the open-ring and closed-ring isomers upon irradiation with UV or visible light in solution, and that the respective closed-ring isomers show decreased fluorescence properties compared with the open-ring isomers. Moreover, the open-ring and closed-ring isomers display high selectivity toward Fe 3+, such that the addition of Fe3+ obviously suppresses their fluorescence intensity.

Aldol Reactions of γ- and ε-Methylene in 5-Membered Heteroaromatic Compounds

5-Methyl-2-thiophenecarboxaldehyde (1a) and 3-methyl-2-thiophenecarboxaldehyde (6) underwent intermolecular aldol reactions in which the methyl group behaved as active methylene in the presence of potassium cyanide. 5-Methylfurfural (1b) gave only 5,5'-di
