Check Digit Verification of cas no
The CAS Registry Mumber 69898-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,8,9 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69898-40:
(7*6)+(6*9)+(5*8)+(4*9)+(3*8)+(2*4)+(1*0)=204
204 % 10 = 4
So 69898-40-4 is a valid CAS Registry Number.

A thermodynamic study on phthalide-type dyes in aqueous alcohol solutions
Kim, Jae-Uk,Yoo, Jeong-Yeol,Kim, Jong-Gyu
, p. 1980 - 1984 (2015/08/18)
Phthalide-type dyes in aqueous variable alcohol solution were studied by UV-vis absorption spectroscopy. In this study, 7-[4-(diethylamino)-2-ethoxyphenyl]-7-(1-ethyl-2-methyl-1H-indol-3-yl)furo[3,4-b]pyridin-5(7H)-one ("Blue-63") was used. Generally, a blue shift is observed from dyes in higher-carbon-number-alcohol solvents. The results indicated the dye equilibrium constant in aqueous alcohol solutions. The equilibrium constant (K), Gibbs energy change (ΔG), enthalpy change (ΔH), and entropy change (ΔS) of the dye, depending on temperature change, were also calculated using UV absorbance.
Transparent recording medium
-
, (2008/06/13)
A transparent recording medium is disclosed which can directly record a fine, precise image. With the recording medium, a compact, fine image occupying a small storage space can be easily enlarged and confirmed by an enlarged projection. It is prepared by applying a coating liquid for recording comprising a developer in which a hydroxyl group with a developing function is blocked by an N-substituted carbamoyl group or an O-substituted oxycarbonyl group, an iron salt of an organic acid or a leuco dye, a near-infrared absorbing agent, and a binder, uniformly dissolved in an organic solvent such as MEK, to a transparent plastic substrate, and drying to obtain a transparent recording layer with a thickness of 3 μm to 8μm. A visible, precise, fine direct image can then be recorded using a semiconductor laser beam.
