Check Digit Verification of cas no

The CAS Registry Mumber 84445-92-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,4,4 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 84445-92:
(7*8)+(6*4)+(5*4)+(4*4)+(3*5)+(2*9)+(1*2)=151
151 % 10 = 1
So 84445-92-1 is a valid CAS Registry Number.

Synthesis method of key raw material 2-chloro-6-methylaniline of dasatinib

-

Paragraph 0016; 0033; 0035; 0038; 0040, (2021/04/21)

The invention discloses a synthetic method of a key raw material 2-chloro-6-methylaniline of dasatinib. The method comprises the following steps: firstly, protecting a 1-site amino group of 2-nitro-6-methylaniline, then reducing a 2-site nitro group of 2-nitro-6-methylaniline into an amino group, then carrying out diazotization reaction, carrying out chlorine substitution on the 2-site amino group by using cuprous chloride, and finally, carrying out acidolysis to remove a 1-site amino protecting group to obtain 2-chlorine-6-methylaniline. The method has the advantages of cheap and easily available raw materials, easily controllable reaction, simple operation steps, simple post-treatment, recyclable solvents, small pollution, and suitableness for large-scale production of generative enterprises.
