Check Digit Verification of cas no

The CAS Registry Mumber 170856-84-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,8,5 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 170856-84:
155 % 10 = 5
So 170856-84-5 is a valid CAS Registry Number.

Copper-catalyzed enantioselective additions to oxocarbenium ions: Alkynylation of isochroman acetals

Maity, Prantik,Srinivas, Harathi D.,Watson, Mary P.

supporting information; experimental part, p. 17142 - 17145 (2011/12/13)

We have developed an enantioselective, copper(I)-catalyzed addition of terminal alkynes to racemic isochroman acetals. This method is one of the first transition-metal-catalyzed approaches to enantioselective additions to prochiral oxocarbenium ions. In this reaction, TMSOTf is used to form the oxocarbenium ion in situ under conditions compatible with simultaneous formation of the chiral copper acetylide. By using a bis(oxazoline) ligand, good yields and enantioselectivities are observed for a variety of enantioenriched 1-alkynyl isochromans.
