Check Digit Verification of cas no

The CAS Registry Mumber 120686-00-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,6,8 and 6 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 120686-00:
102 % 10 = 2
So 120686-00-2 is a valid CAS Registry Number.

A process for the synthesis of intermediates in the preparation method of the huperzine-a


Paragraph 0027; 0040; 0042; 0043, (2018/11/03)

The invention discloses a preparation method of an intermediate for synthesizing huperzine A. The preparation method comprises the following steps: substituting 3-bromine-6-methoxy-2-methyl pyridine taken as a raw material with N-bromosuccinimide so as to obtain a substitution product; carrying out a reaction on the substitution product and methyl acetoacetate and then carrying out ring closing reaction under the action of cuprous iodide so as to obtain 2-methoxy-6-hydroxy-7,8-dihydro-5-quinoline carboxylic methyl ester. According to the method provided by the invention, the synthesis reaction cost is low, so that the production cost is effectively lowered; the reaction conditions are moderate, so that the safety of operating personnel is ensured; a refining process is convenient and simple to operate; the intermediate obtained via the reaction is good in quality, high in yield and good in environmental friendliness.
