Check Digit Verification of cas no
The CAS Registry Mumber 57117-35-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,1,1 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 57117-35:
(7*5)+(6*7)+(5*1)+(4*1)+(3*7)+(2*3)+(1*5)=118
118 % 10 = 8
So 57117-35-8 is a valid CAS Registry Number.

Role of copper chloride in the formation of polychlorinated dibenzo-p-dioxins and dibenzofurans during incineration
Hatanaka, Takeshi,Kitajima, Akio,Takeuchi, Masao

Combustion experiments in a laboratory-scale fluidized-bed reactor were performed to elucidate the role of copper chloride in formation of polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) during model waste incineration. The amounts of PCDDs and PCDFs formed, the homologue profiles, and the isomer distributions were measured in the flue gas from incineration of model wastes containing various levels of copper. A correlation was found between the Cu content of the waste and the proportion of each congener. An increase in copper enhanced the formation of certain congeners, showing that copper acts as a catalyst for formation of PCDDs and PCDFs. An increase in the copper content of the waste decreased the CO concentration in the flue gas and reduced the formation of PCDDs and PCDFs during incineration. This indicates that copper also works as an oxidation catalyst to promote combustion, leading to lower concentrations of products of incomplete combustion. It is indispensable to consider both roles of the catalyst, i.e., enhancement and suppression, in the formation of PCDDs and PCDFs during waste incineration, which are estimated separately from the isomer distributions and the amounts of PCDDs and PCDFs formed.

The 38 positional isomers of tetrachlorodibenzofuran have been synthesized by pyrolysis of specific polychlorinated biphenyl congeners, ultraviolet photolysis of pentachlorodibenzofurans, and chlorination of trichlorodibenzofurans by aromatic substitution.The specificity of these reactions in combinatiuon with capillary column gas chromatography with mass spectrometric detection has allowed each of these isomers to be identified based on their relative elution order.
