1223371-26-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1223371-26-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,3,3,7 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1223371-26:
(9*1)+(8*2)+(7*2)+(6*3)+(5*3)+(4*7)+(3*1)+(2*2)+(1*6)=113
113 % 10 = 3
So 1223371-26-3 is a valid CAS Registry Number.

A General and Selective Rhodium-Catalyzed Reduction of Amides, N-Acyl Amino Esters, and Dipeptides Using Phenylsilane

Das, Shoubhik,Li, Yuehui,Lu, Liang-Qiu,Junge, Kathrin,Beller, Matthias

, p. 7050 - 7053 (2016)

This article describes a selective reduction of functionalized amides, including N-acyl amino esters and dipeptides, to the corresponding amines using simple [Rh(acac)(cod)]. The catalyst shows excellent chemoselectivity in the presence of different sensitive functional moieties. A selective reduction of functionalized amides, including N-acyl amino esters and dipeptides, to the corresponding amines using simple [Rh(acac)(cod)] is described (see scheme). The catalyst shows excellent chemoselectivity in the presence of different sensitive functional moieties. Even the selective reduction of a secondary amide bond in the presence of a ketone is possible.
