Check Digit Verification of cas no

The CAS Registry Mumber 7120-02-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,2 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7120-02:
(6*7)+(5*1)+(4*2)+(3*0)+(2*0)+(1*2)=57
57 % 10 = 7
So 7120-02-7 is a valid CAS Registry Number.

Method for synthesizing 2-guanidinothiazole compound by one-pot process

-

Paragraph 0014, (2020/11/09)

According to the invention, a substituted methyl ketone compound is innovatively used as a raw material, amidinothiourea is added into an alcohol solvent under the conditions of halogeno salt MX and Oxone, and a one-pot process one-step reaction is carried out to obtain the target 2-guanidinothiazole compound. Common methyl ketone is used for replacing an alpha-halogenated carbonyl compound whichis high in price and toxicity, MX which is low in price and easy to obtain is used as a halogen source, the method is novel, raw materials and reagents are cheap, reaction conditions are mild, and operation is easy and convenient, therefore low-cost, convenient and rapid synthesis of the 2-guanidinothiazole compound is achieved.
