Check Digit Verification of cas no

The CAS Registry Mumber 57500-51-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,5,0 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 57500-51:
(7*5)+(6*7)+(5*5)+(4*0)+(3*0)+(2*5)+(1*1)=113
113 % 10 = 3
So 57500-51-3 is a valid CAS Registry Number.

Synthesis method of 4-chlorothiophene-2-carbonyl derivative

-

Paragraph 0038-0040, (2019/03/08)

The invention discloses a synthesis method of a 4-chlorothiophene-2-carbonyl derivative. A thiophene-2-carbonyl derivative is used as a raw material and reacts with symclosene and aluminum trichloride, and liquid separation and concentration are performed to obtain the 4-chlorothiophene-2-carbonyl derivative. The synthesis method adopts one-step reaction, the yield is not lower than 80%, the production process is decreased while the yield is improved, and the cost is reduced; the used raw materials and reagents are easy to obtain, reaction conditions are mild, post-treatment and purification is easy to operate, and large-scale production can be achieved.
