Check Digit Verification of cas no
The CAS Registry Mumber 849062-36-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,0,6 and 2 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 849062-36:
(8*8)+(7*4)+(6*9)+(5*0)+(4*6)+(3*2)+(2*3)+(1*6)=188
188 % 10 = 8
So 849062-36-8 is a valid CAS Registry Number.

Paragraph 0013-0015; 0028- 0030; 0043-0045; 0058-0060, (2018/01/12)
The invention discloses a preparation process for 3-methyl-5-methoxybenzenesulfonyl chloride. The process comprises the following steps: 3,5-dibromotoluene is used as an initial raw material, the 3,5-dibromotoluene is subjected to a boronic acidification reaction, thus 3-methyl-5-bromophenylboronic acid is obtained, the 3-methyl-5-bromophenylboronic acid is subjected to an oxidation reaction, thus 3-methyl-5-bromophenol is obtained, the 3-methyl-5-bromophenol is subjected to a substitution reaction, thus 3-methyl-5-bromoanisoles is obtained, the 3-methyl-5-bromoanisoles is subjected to sulfonation, thus 3-methyl-5-methoxybenzenesulfonate is obtained, the 3-methyl-5-methoxybenzenesulfonate is subjected to a substitution reaction, and therefore the objective compound 3-methyl-5-methoxybenzenesulfonyl chloride is obtained. According to the above route, the raw materials are easy to obtain, post-treatment is simple, convenient and easy to implement, a yield is relatively high, and the process has relatively-good application value.
