Check Digit Verification of cas no

The CAS Registry Mumber 1292820-63-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,2,8,2 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1292820-63:
(9*1)+(8*2)+(7*9)+(6*2)+(5*8)+(4*2)+(3*0)+(2*6)+(1*3)=163
163 % 10 = 3
So 1292820-63-3 is a valid CAS Registry Number.

Highly diastereo- and enantioselective vinylogous Mannich reactions of fluorinated aldimines with siloxyfurans

Zhao, Qian-Yi,Yuan, Zhi-Liang,Shia, Min

, p. 637 - 643 (2011/04/25)

A highly regio- and enantioselective asymmetric vinylogous Mannich reaction of readily available fluorinated aldimines bearing a chiral auxiliary [(S)-1-phenylethyl group] with siloxyfurans to afford chiral fluorine-containing γ-butenolide or γ-lactone derivatives has been developed in the presence of silver acetate (10 mol%) and axially chiral phosphine-oxazoline ligand L1 (11 mol%). In most cases, the corresponding fluorinated adducts were obtained in high yields, good to excellent enantiomeric excesses and up to > 20:1 dr.
