Check Digit Verification of cas no

The CAS Registry Mumber 5521-57-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,2 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5521-57:
(6*5)+(5*5)+(4*2)+(3*1)+(2*5)+(1*7)=83
83 % 10 = 3
So 5521-57-3 is a valid CAS Registry Number.

Paragraph 0037; 0044-0045; 0048; 0055-0056; 0059; 0066-0067, (2020/11/25)

The invention belongs to the field of chemical synthesis, and relates to a preparation method, product and application of 2-amino-5-methylpyrazine. The preparation method comprises the following steps: reacting 2-aminomalonamide with pyruvic aldehyde to generate 2-methyl-5-hydroxy-4-pyrazinamide; enabling 2-methyl-5-hydroxy-4-pyrazinamide to react with phosphorus oxychloride so as to generate 2-methyl-5-chloro-4-cyanopyrazine; carrying out a hydrogenation reaction on the 2-methyl-5-chloro-4-cyanopyrazine to generate 2-methyl-4-cyanopyrazine, and hydrolyzing the 2-methyl-4-cyanopyrazine to obtain 2-methyl-4-amide pyrazine; and carrying out Hofmann degradation on the 2-methyl-4-amide pyrazine so as to obtain the 2-methyl-5-aminopyrazine. The method belongs to a brand-new 2-amino-5-methylpyrazine preparation method, is simple and convenient to operate, high in yield and low in cost, and is suitable for industrial large-scale production.
