104873-15-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 104873-15-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,7 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 104873-15:
(8*1)+(7*0)+(6*4)+(5*8)+(4*7)+(3*3)+(2*1)+(1*5)=116
116 % 10 = 6
So 104873-15-6 is a valid CAS Registry Number.

The present invention provides an improved process for the preparation of methyl carbapenem derivative of formula (I) or its pharmaceutically acceptable salts or hydrates thereof in a pure form.

IMPROVED METHOD FOR THE CRYSTALLIZATION OF INTERMEDIATES OF CARBAPENEM ANTIBIOTICS

-

Page/Page column 10, (2009/01/24)

The present invention relates to an azetidinone compound extremely useful as a common intermediate for the synthesis of 1β-methylcarbapenem compounds. The present invention provides a crystallization method to obtain a crystal which has a higher quality and a higher stability than a conventional crystal and is excellent in filterability at the time of recovering crystal; an azetidinone compound having a low content of impurity; and an azetidinone compound which has a controlled particle size distribution of crystals and improved handleability and stability. The crystallization is carried out by adding a hydrocarbon solvent to a solution in which an azetidinone compound extremely useful as a common intermediate for the synthesis of 1β-methylcarbapenem compounds is dissolved in the presence of a seed crystal in an amount of 200% by weight or less based on the weight of the azetidinone compound. According to the method, the crystal having a high quality and a high stability and excellent filterability at the time of recovering the crystal can be obtained.
