5651-50-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5651-50-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,5 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5651-50:
(6*5)+(5*6)+(4*5)+(3*1)+(2*5)+(1*0)=93
93 % 10 = 3
So 5651-50-3 is a valid CAS Registry Number.

Method for synthesizing 2-methyl-4H-benzo[d][1,3] oxathiin-4-one

-

Paragraph 0012-0015, (2020/01/08)

The invention relates to the technical field of fine chemical industry, and discloses a method for synthesizing 2-methyl-4H-benzo[d][1,3] oxathiin-4-one promoted by NFSI. Specific steps are as follow:2-ethylthiobenzoic acid is used as raw material, N-fluorobenzenesulfonimide [NFSI] is used as an additive, and the target product 2-methyl-4H-benzo[d][1,3] oxathiin-4-one can be obtained by reactingin acetonitrile at 100 DEG C for 24 hours. This method is easy to operate and uses 2-ethylthiobenzoic acid as the reaction raw material and NFSI is used as the additive to synthesize the target product in a green and efficient one-step way, which has potential application value.
