Cefomonil (TAP).

Check Digit Verification of cas no

The CAS Registry Mumber 41444-66-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,4,4 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 41444-66:
100 % 10 = 0
So 41444-66-0 is a valid CAS Registry Number.

Medicinal cefsulodin sodium compound and preparation method thereof


Paragraph 0069; 0070; 0071, (2017/07/21)

The invention relates to the technical field of medicine, in particular to a medicinal cefsulodin sodium compound and a preparation method thereof. The preparation method of the medicinal cefsulodin sodium compound includes steps: 1) preparation of 3-(4-pyridinecarboxamide-1-methylene)-7-amino-cephalosporanic acid; 2) preparation of D-sulfophenylacetyl chloride; 3) preparation of D-sulfocephalosporanic acid; 4) preparation of cefsulodin sodium. The technical defects of high cost, low safety and low yield of existing preparation methods are overcome; by adoption of a silicon reagent method for preparation of the cefsulodin sodium compound, racemate controllability, high safety, high yield and high quality are realized, starting materials are easy to acquire, reaction conditions of each step are mild, equipment requirements are low, a single solvent is adopted and convenient to recycle, the requirement on environment friendliness can be met, and the method is suitable for large-scale industrial production.

Process for preparing cefsulodin sodium


Page/Page column 11; 12, (2009/12/05)

The invention is directed to an improved process for preparing cefsulodin sodium. The process involves: (i) dissolving cefsulodin in a solvent comprising an organic solvent to provide a solution of cefsulodin, (ii) adding about 1 equivalent of a sodium salt of a base to the solution of cefsulodin to provide a solution of cefsulodin sodium, and (iii) separating the cefsulodin sodium from the solution of cefsulodin sodium.
