Check Digit Verification of cas no

The CAS Registry Mumber 574-42-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,7 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 574-42:
(5*5)+(4*7)+(3*4)+(2*4)+(1*2)=75
75 % 10 = 5
So 574-42-5 is a valid CAS Registry Number.

Kato, Yuichi,Inoue, Tomoka,Furuyama, Yuuki,Ohgane, Kenji,Sadaie, Mahito,Kuramochi, Kouji

supporting information, (2021/11/16)

The deoxygenation of tertiary and secondary alcohols to give the corresponding alkanes is conventionally performed using an organosilane and a strong acid. In this study, a deoxygenation method was developed for tertiary and secondary alcohols, using trimethylsilane and trimethylsilyl iodide generated in situ from sodium borohydride and trimethylsilyl chloride, and trimethylsilyl chloride and potassium iodide, respectively. With our method, tertiary and secondary alcohols, which provided stable carbocations, were converted into the corresponding alkanes. This paper also presents the optimization of the reaction conditions, the reaction mechanism, as well as the scope and limitations of the method.

The invention discloses a method for synthesizing ether by catalyzing alcohol through trimethyl halosilane. According to the method, under the conditions of air or nitrogen atmosphere, no solvent andno transition metal catalyst, an alcohol compound is directly used as a raw material, trimethyl halosilane is used as a catalyst, and symmetric or asymmetric ether is synthesized through one-step selective dehydration reaction. According to the method, the use of strong acid, strong base and organic primary halides with high toxicity, instability and higher price is avoided, the synthesis steps are shortened, the synthesis efficiency is improved, the reaction has good selectivity, and a target ether product can be obtained preferentially.

Switchable iridium hydride catalysts for controlling selectivity of alcohol oxidation

Albrecht, Martin,Olivares, Marta

, (2020/05/25)

Novel pyridyl-triazolylidene iridium(III) hydride complexes have been synthesized through modification of the analogous iridium chloride complexes. The dehydration of alcohols was used to probe the catalytic potential of the iridium chloride compounds and the influence of the electronic modification on the pyridyl-triazolylidene ligand scaffolds. The incorporation of electron donor substituents on the triazolylidene heterocycle considerably enhanced the catalytic activity of the coordinated iridium center towards the catalytic dehydration of alcohols. Moreover, the iridium hydride compounds are switchable catalysts that perform either alcohol dehydration or dehydrogenation. Their selectivity was predictably triggered by the presence or absence of HPF6 in the catalytic reaction.
