892493-69-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 892493-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,2,4,9 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 892493-69:
(8*8)+(7*9)+(6*2)+(5*4)+(4*9)+(3*3)+(2*6)+(1*9)=225
225 % 10 = 5
So 892493-69-5 is a valid CAS Registry Number.

Copper(I) mediated cross-coupling of amino acid derived organozinc reagents with acid chlorides

Hjelmgaard, Thomas,Tanner, David

, p. 1796 - 1805 (2008/02/05)

This paper describes the development of a straightforward experimental protocol for copper-mediated cross-coupling of amino acid derived β-amido-alkylzinc iodides 1 and 3 with a range of acid chlorides. The present method uses CuCN·2LiCl as the copper source and for organozinc reagent 1 the methodology appears to be limited to reaction with more stable acid chlorides, providing the desired products in moderate yields. When applied to organozinc reagent 3, however, the protocol is more general and provides the products in good yields in all but one of the cases tested. The Royal Society of Chemistry 2006.
