1438399-17-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1438399-17-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,8,3,9 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1438399-17:
(9*1)+(8*4)+(7*3)+(6*8)+(5*3)+(4*9)+(3*9)+(2*1)+(1*7)=197
197 % 10 = 7
So 1438399-17-7 is a valid CAS Registry Number.

A highly stereoselective synthesis of glycidic amides based on a new class of chiral sulfonium salts: Applications in asymmetric synthesis

Sarabia, Francisco,Vivar-García, Carlos,García-Castro, Miguel,García-Ruiz, Cristina,Martín-Gálvez, Francisca,Sánchez-Ruiz, Antonio,Chammaa, Samy

, p. 15190 - 15201 (2013/01/15)

A new type of chiral sulfonium salts that are characterized by a bicyclic system has been designed and synthesized from α-amino acids. Their corresponding ylides, which were prepared by basic treatment of the sulfonium salts, reacted smoothly with a broad array of simple and chiral aldehydes to provide trans-epoxy amides in reasonable to very good yields and excellent stereoselectivities (>98 %). The obtained epoxy amides were found to be useful as synthetic building blocks. Thus, they were reduced into their corresponding epoxy alcohols and subjected to oxirane-ring-opening reactions with different types of nucleophiles.
