Check Digit Verification of cas no
The CAS Registry Mumber 77449-43-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,4 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77449-43:
(7*7)+(6*7)+(5*4)+(4*4)+(3*9)+(2*4)+(1*3)=165
165 % 10 = 5
So 77449-43-5 is a valid CAS Registry Number.

METHOD OF PREPARING INTERMEDIATES OF PENEM ANTIBIOTICS
-
Page/Page column 28; 30, (2009/06/27)
The present invention relates to a method of preparing bicyclic keto esters, which are intermediates for carbapenem-based antibiotics. The method of preparing carbapenem-based antibiotic intermediates according to the present invention has not only the fast reaction rate using co-catalysts and specific reaction solvents which may be allowed to have high activity of rhodium catalysts, but also reduces the amount of expensive rhodium catalysts. Therefore, the present invention is very economical and useful, in industrial aspects.
