Check Digit Verification of cas no
The CAS Registry Mumber 1947-33-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,4 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1947-33:
(6*1)+(5*9)+(4*4)+(3*7)+(2*3)+(1*3)=97
97 % 10 = 7
So 1947-33-7 is a valid CAS Registry Number.

A convenient approach to arenediazonium tosylates

Herein we present a mild, simple and environmentally friendly diazotization protocol of aromatic and heteroaromatic anilines into stable diazonium salts that surpass previously reported procedures. The reaction proceeds with tert-butyl nitrite in the presence of an equimolar amount or small excesses of p-toluenesulfonic acid in ethyl acetate, at room temperature. o-Phenylenediamines yield benzotriazolium tosylates. The resulting diazonium tosylates proved to be bench stable over a long period of time. In selected examples, diazonium salts were let to react with activated aromatic compounds including 2-naphthol and aniline derivatives into the corresponding azo dyes.

[3+2]-Cycloaddition of arenediazonium salts with diazo compounds (earlier exemplified only for trimethylsilyldiazomethane and 2,2,2-trifluorodiazoethane) has been developed to include a wide range of readily available α-diazocarbonyl compounds. The resulting 2-aryl-5-acyl-2 H -tetrazoles are of high value in medicinal chemistry.

Changes in major charge transport of graphene channel transistors in terms of the spatial orientation of adsorbed functional molecules were demonstrated. In contrast to the horizontally (physically) bound molecules, the vertically (chemically) bound molecules did not change major charge carriers of graphene channels, revealing the molecular orientation-dependent doping effects.
