Check Digit Verification of cas no

The CAS Registry Mumber 39736-29-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,7,3 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 39736-29:
(7*3)+(6*9)+(5*7)+(4*3)+(3*6)+(2*2)+(1*9)=153
153 % 10 = 3
So 39736-29-3 is a valid CAS Registry Number.

Synthesis method of ethyl 4-amino-2-(methylthio)thiazole-5-carboxylate

-

Paragraph 0032; 0035, (2019/11/20)

The invention belongs to the technical field of pharmaceutical intermediates, and relates to a synthesis method of ethyl 4-amino-2-(methylthio)thiazole-5-carboxylate. The method includes the followingsteps that an aqueous solution of cyanamide is mixed with ethanol, carbon disulfide and a potassium hydroxide solution are added for reaction, and a precipitated solid is subjected to suction filtration and drying to obtain an intermediate A; the intermediate A is dissolved in a mixed solution of ethanol and water, an iodomethane ethanol solution is dropped for reaction, and an intermediate B isobtained through concentration and drying; the intermediate B, ethyl chloroacetate and triethylamine are subjected to a reflux reaction in ethanol, and the obtained solution is concentrated, washed and re-crystallized to obtain ethyl 4-amino-2-(methylthio)thiazole-5-carboxylate. The cost of raw materials is low, the yield of by-products is low, the product yield is high, and the method is suitablefor scale-up production.
