Check Digit Verification of cas no
The CAS Registry Mumber 29446-15-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,4,4 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 29446-15:
(7*2)+(6*9)+(5*4)+(4*4)+(3*6)+(2*1)+(1*5)=129
129 % 10 = 9
So 29446-15-9 is a valid CAS Registry Number.

Hydrogen bonding promoted simple and clean photo-induced reduction of C-X bond with isopropanol

We herein report a simple and clean photo-induced metal-free reduction of C-X bond under an atmosphere of air at room temperature. Isopropanol is used as both the reducing reagent and solvent. Various functional groups (acids, esters, alcohols, anilines, phenols, indoles, pyridines, cyano and trifluoromethyl groups) and other heterocyclic compounds are tolerated. Different organic halides (including C-I, C-Br and C-Cl bonds) can be dehalogenated with moderate to excellent yields. Polyhalides are also reduced chemoselectively and efficiently. DFT calculation suggests a six-membered ring transition state via C-X H-O hydrogen bonding to decrease the activation energy.
Mono- to tri-chlorinated dibenzodioxin (CDD) and dibenzofuran (CDF) congeners/homologues as indicators of CDD and CDF emissions from municipal waste and waste/coal combustion
Gullett, Brian K.,Wikstroem, Evalena
, p. 1015 - 1019 (2007/10/03)
Total homologue concentrations and select congener concentrations from amongst the mono- to tri-chlorinated dibenzodioxins (CDDs) and dibenzofurans (CDFs) are used to model both Total (mono- to octa-) CDD + CDF emissions and the toxicity equivalent (TEQ) of the 2,3,7,8-chlorine-substituted emissions. Analysis of emission data from two facilities indicates that use of total homologue concentrations shows limited, facility-specific correlations with Total CDDs/CDFs and TEQ. Concentrations of select mono- to tri-CDD/CDF congeners show promising correlation with CDD/CDF TEQ across facilities, suggesting that these compounds can act as TEQ indicators.

Synthesis of mixed halogenated dibenzodioxins (X = Br, Cl)
Jay,Stieglitz
, p. 987 - 991 (2007/10/03)
The conversion of dibenzodioxin with CuCl2x2H2O and CuBr2 results in polyhalogenated dibenzodioxins. Besides the chlorinated compounds, bromination stages 1 to 5 are obtained at chlorination levels of 0 to 7 for monobromo-, 0 to 7 for dibromo-, 0 to 4 for tribromo-, 0 to 3 for tetrabromo-, and 0 to 1 for pentabromodibenzodioxin. The 2,3,7,8 position is halogenated preferentially.
