Check Digit Verification of cas no

The CAS Registry Mumber 70393-66-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,3,9 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 70393-66:
(7*7)+(6*0)+(5*3)+(4*9)+(3*3)+(2*6)+(1*6)=127
127 % 10 = 7
So 70393-66-7 is a valid CAS Registry Number.

Method for synthesizing 3-substituted aminobenzo [c] isothiazole derivative

-

Paragraph 0064-0066, (2020/12/29)

The invention provides a method for synthesizing a 3-substituted aminobenzo [c] isothiazole derivative, which comprises the following steps: by using an amide N-substituted benzamide compound as an initial raw material, carrying out carbonyl oxygen sulfur replacement reaction and cyclization reaction to obtain the 3-substituted aminobenzo [c] isothiazole derivative. According to the method for synthesizing the 3-substituted aminobenzo [c] isothiazole derivative, the whole synthesis route is short in step, good in repeatability, mild in operation condition and high in safety, large-scale production and industrial popularization are facilitated, application of green and environment-friendly industrial production is facilitated, and wide application prospects are achieved.
