Check Digit Verification of cas no

The CAS Registry Mumber 343944-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,9,4 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 343944-91:
(8*3)+(7*4)+(6*3)+(5*9)+(4*4)+(3*4)+(2*9)+(1*1)=162
162 % 10 = 2
So 343944-91-2 is a valid CAS Registry Number.

An aryl alkyl thioether compound and its synthetic method

-

Paragraph 0126-0129, (2019/02/04)

The invention discloses a synthetic method of an aryl alkyl thioether compound shown as formula (II), and the synthetic method is as follows: at room temperature and in a water phase, using triazene and haloalkane as reaction raw materials, using Na2S2O3 as a vulcanization reagent for reaction under the promotion effect of a copper catalyst and a Lewis acid to obtain the aryl alkyl thioether compound. The advantages of the synthetic method are as follows: reaction is efficient and yield is high; the vulcanization reagent is cheap, easy to obtain, stable, and free of irritating smell; the reaction is carried out in the solvent green water, the reaction is free of addition of a phase transfer catalyst and a volatile organic solvent, and is environmentally friendly; the reaction is carried out at room temperature, is mild in condition; the catalyst copper sulfate used in the reaction is cheap and economic reaction; the reaction substrate is easy in preparation; after amplification, the reaction efficiency is higher.

Sulfide synthesis through copper-catalyzed C-S bond formation under biomolecule-compatible conditions

Zhang, Yonghong,Li, Yiming,Zhang, Xiaomei,Jiang, Xuefeng

supporting information, p. 941 - 944 (2015/01/09)

We report here an efficient and mild method for constructing C-S bonds. The reactions were carried out with Na2S2O3 as a sulfurating reagent, CuSO4 as a catalyst, and water as solvent without any surfactant. The products were achieved in moderate to excellent yields at room temperature under air. Notably, this reaction is compatible with various biomolecules including amino acids, oligosaccharides, nucleosides, proteins, and cell lysates. This journal is
