182161-95-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 182161-95-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,1,6 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 182161-95:
(8*1)+(7*8)+(6*2)+(5*1)+(4*6)+(3*1)+(2*9)+(1*5)=131
131 % 10 = 1
So 182161-95-1 is a valid CAS Registry Number.

Chirally templated boronic acid Mannich reaction in the synthesis of optically active α-amino acids

Currie, Gordon S.,Drew, Michael G.B.,Harwood, Laurence M.,Hughes, David J.,Luke, Richard W.A.,Vickers, Richard J.

, p. 2982 - 2990 (2007/10/03)

Adducts from diastereoselective Mannich-type reactions of aldehydes, 2-furylboronic acid and the chiral amine template (S)-5-phenylmorpholin-2-one, were used in the synthesis of a series of enantiomerically pure D-α-amino acids. The direction of diastereocontrol was proved by X-ray crystallography analysis of the reaction products. Results indicated that sequential degradation of diastereomically pure N-furfurylmorpholinones obtained by boronic Mannich condensation, could be carried out to produce amino acids of high optical purity.
