26891-59-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 26891-59-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,8,9 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 26891-59:
(7*2)+(6*6)+(5*8)+(4*9)+(3*1)+(2*5)+(1*9)=148
148 % 10 = 8
So 26891-59-8 is a valid CAS Registry Number.

SINGLE-STEP SYNTHESIS METHOD OF ARYL THIOL AND APPLICATION THEREOF

-

Paragraph 0033; 0034; 0035; 0077; 0080-0082, (2017/09/02)

The present invention relates to a single-step synthesis method of aryl thiol, and more specifically, to a method of synthesizing aryl thiol in a single-step by making aryl halide react with alkane dithiol in the presence of a transition metal catalyst. According to the present invention, a single-step synthesis method using the transition metal catalyst, the synthesis method which is capable of synthesizing aryl thiol from aryl halide at a high yield, can be provided. Various aryl halides may be applied to the synthesis method. Further, the synthesis method has advantages that an easily usable reagent may be used, operations are simple, and reactions can be performed under mild conditions. In addition, the synthesized aryl thiol may be used in the synthesis of advanced molecules such as diaryl sulfides and benzothiophenes.COPYRIGHT KIPO 2017
