884865-77-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 884865-77-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,4,8,6 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 884865-77:
(8*8)+(7*8)+(6*4)+(5*8)+(4*6)+(3*5)+(2*7)+(1*7)=244
244 % 10 = 4
So 884865-77-4 is a valid CAS Registry Number.

Highly Diastereoselective and Irreversible Aldol Reactions of N -Sulfonylimidates

Bartrum, Hannah E.,Carret, Sébastien,Poisson, Jean-Fran?ois

supporting information, p. 3413 - 3419 (2016/09/09)

A mild method for the aldolization of N-sulfonylimidates was developed. The reaction proceeds in excellent diastereoselectivity to provide a range of useful β-hydroxyimidates in high yield. The innate reversibility of the reaction is suppressed by the use of a titanium complex as a Lewis acid.

A new entry of copper-catalyzed four-component reaction: Facile access to α-Aryl β-hydroxy imidates

Yoo, Eun Jeong,Park, Sae Hume,Lee, Sang Hyup,Chang, Sukbok

supporting information; experimental part, p. 1155 - 1158 (2009/08/07)

α-Aryl β-hydroxy imidates are efficiently obtained by the four-component reaction of ethyl glyoxylates, aryl acetylenes, sulfonyl azides, and alcohols using a copper catalyst. The developed procedure is characterized by high selectivity, mild reaction con
