24003-17-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24003-17-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,0,0 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 24003-17:
(7*2)+(6*4)+(5*0)+(4*0)+(3*3)+(2*1)+(1*7)=56
56 % 10 = 6
So 24003-17-6 is a valid CAS Registry Number.

Catalytic, Asymmetric α-Chlorination of Acid Halides

France, Stefan,Wack, Harald,Taggi, Andrew E.,Hafez, Ahmed M.,Wagerle, Ty R.,Shah, Meha H.,Dusich, Crystal L.,Lectka, Thomas

, p. 4245 - 4255 (2004)

We present a full account of a tandem catalytic, asymmetric chlorination/esterification process that produces highly optically enriched α-chloroesters from inexpensive, commercially available acid halides using cinchona alkaloid derivatives as catalysts and polychlorinated quinones as halogenating agents. We have performed kinetics and control experiments to investigate the reaction mechanism and establish conditions under which the reactions can be best performed. We have developed NaH and NaHCO3 shuttle base systems as the easiest and most cost-effective ways of conducting the reactions, rendering the methodology economically competitive with known chiral halogenation procedures. We have also demonstrated the utility of our reactions by converting the products to synthetically useful derivatives.
