Check Digit Verification of cas no
The CAS Registry Mumber 98006-91-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,0 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 98006-91:
(7*9)+(6*8)+(5*0)+(4*0)+(3*6)+(2*9)+(1*1)=148
148 % 10 = 8
So 98006-91-8 is a valid CAS Registry Number.

, (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.
