Check Digit Verification of cas no
The CAS Registry Mumber 13243-99-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,2,4 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13243-99:
(7*1)+(6*3)+(5*2)+(4*4)+(3*3)+(2*9)+(1*9)=87
87 % 10 = 7
So 13243-99-7 is a valid CAS Registry Number.

Paragraph 0021; 0022; 0023; 0024-0031, (2016/10/31)
The invention discloses a preparation method of 3-carboxyl-4-hydroxy-acetoacetanilide. The preparation method comprises the following steps: pumping a prescribed amount of soft water into a reaction kettle, adding caustic soda flakes to the reaction kettle, slowly adding 5-aminosalicylic acid to a sodium hydroxide solution, and adjusting and determining the pH value of the above obtained mixed solution to be about 7; and adjusting the temperature in the reaction kettle to be 18-27DEG C, slowly adding diketene in a dropwise manner, carrying out heat insulation by using the natural temperature, discharging the obtained material to a neutralization and crystallization kettle, filtering, carrying out centrifuge dewatering, and drying to obtain a finished product. The method has the advantages of simple operating steps, good working environment, mild reaction conditions, no special requirements on a device, realization of good quality and high yield of the product, and low energy consumption, and the 3-carboxyl-4-hydroxy-acetoacetanilide prepared through the method is not likely to agglomerate.
