Check Digit Verification of cas no
The CAS Registry Mumber 24387-68-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,3,8 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 24387-68:
(7*2)+(6*4)+(5*3)+(4*8)+(3*7)+(2*6)+(1*8)=126
126 % 10 = 6
So 24387-68-6 is a valid CAS Registry Number.

Paragraph 0034; 0036-0037; 0041-0046, (2020/04/22)
The invention discloses a preparation method of 2, 6-dichloropyrazine. The method comprises the following steps: taking glycine and glyoxal as raw materials, carrying out ammoniation and cyclization reactions to prepare 2-hydroxypyrazine sodium; and reacting 2-hydroxypyrazine sodium with thionyl chloride under the catalytic action of N,N-diisopropylethylamine to prepare 2-chloropyrazine; wherein pyridine is used as a solvent, and 2-chloropyrazine is subjected to chlorination of chlorine to obtain 2,6-dichloropyrazine. The method has the advantages that the raw material namely glycine is cheapand easily available, and phosphorus oxychloride is not used as a chlorination reagent, so that the generation of organic phosphorus-containing wastewater is greatly reduced, and an effective way is provided for efficient green industrial production of 2, 6-dichloropyrazine.
