Check Digit Verification of cas no
The CAS Registry Mumber 43200-82-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,3,2,0 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 43200-82:
(7*4)+(6*3)+(5*2)+(4*0)+(3*0)+(2*8)+(1*2)=74
74 % 10 = 4
So 43200-82-4 is a valid CAS Registry Number.

Paragraph 0025; 0026, (2017/01/05)
The invention relates to a preparation method of zopiclone for improving sleeping, belonging to the field of medicines. In the preparation process of 6-(5-chlro-2-pyridyl)-5, 7-dioxo-5, 6-dihydropyrrolo[3, 4-b] pyrazine, namely a compound 3, by taking DMAP (dimethylaminopyridine) as a catalyst, in the presence of triethylamine, cyclization is directly carried out to synthesize an intermediate 3. The crude product yield is 85%, the yield is improved, the operation is simplified, and irritant reagents such as acetic anhydride, thionyl chloride, ethyl chloroformate and the like are not used, thereby facilitating production, facilitating recovery of xylene as a solvent and reducing emission of three wastes. Zopiclone is further synthesized by the compound 3. The method is concise in whole line, simple and convenient to operate and more suitable for industrialized production.
IMPROVED PROCESS FOR THE PREPARATION OF ZOPICLONE AND IT'S ENANTIOMERICALLY ENRICHED ISOMER
-
, (2008/12/08)
Present invention relates to an improved process for the preparation of Zopiclone and its enantiomerically enriched isomer (Eszopiclone). 6-(5-Chloropyridin-2- yl)-5-hydroxy-7-oxo-5,6-dihydropyrrolo [3,4-b] pyrazine is reacted with 1-chloro- carbonyl-4-methylpiperazine in the presence of alkali earth metal carbonates, hydroxides or oxides in a solvent medium to give Zopiclone. It is reacted with optically active acid in a mixture of water and water miscible organic solvent followed by work up to give Eszopiclone. The present invention also relates to process for the conversion of (R) or (S) Zopiclone to 6-(5-chloropyrid-2-yl)-5-hydroxy-7-oxo-5,6-dihydro- pyrrolo- [3,4-b] - pyrazine of the intermediate which can be converted to racemic Zopiclone.
