Check Digit Verification of cas no
The CAS Registry Mumber 567-13-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 567-13:
(5*5)+(4*6)+(3*7)+(2*1)+(1*3)=75
75 % 10 = 5
So 567-13-5 is a valid CAS Registry Number.

Paragraph 0025, (2016/11/17)
The invention discloses a method for preparing amino-naphthol-sulfonic acid through catalytic hydrogenation, belonging to the technical field of organic synthesis. The method is characterized by using Raney nickel, Pt/C or Pd/C as a catalyst and carrying out catalytic hydrogenation reaction at a temperature of 50-120 DEG C and a pressure of 0.5-4MPa for 0.5-5 hours, thus preparing amino-naphthol-sulfonic acid, wherein the amount of the added catalyst is 0.5-8% of the mass of added nitroso group or nitro-naphthol-sulfonic acid. The product has liquid chromatography content of more than 98% and yield of more than 90%. The method has the advantages that the process is simple and convenient to operate and avoids equipment corrosion; the product obtained after reaction is completed can be directly used in the next reaction, without after-treatment, and does not generate any solid or liquid waste, thus avoiding the problems of difficulty in solid waste treatment and pollution in sodium hyposulfite processes; the product obtained by applying the process has good quality; and the production process is environment-friendly and green.
