Check Digit Verification of cas no

The CAS Registry Mumber 137654-28-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,5 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 137654-28:
(8*1)+(7*3)+(6*7)+(5*6)+(4*5)+(3*4)+(2*2)+(1*8)=145
145 % 10 = 5
So 137654-28-5 is a valid CAS Registry Number.

Organocatalytic enantioselective Michael addition of α-nitroacetate to α,β-unsaturated enones: A route to chiral γ-nitro ketones and δ-keto esters

Moon, Hyoung Wook,Kim, Dae Young

experimental part, p. 291 - 295 (2011/11/12)

The catalytic enantioselective conjugate addition reaction of α-nitroacetate to α,β-unsaturated enones promoted by chiral bifunctional organocatalysts is described. The treatment of α-nitroacetate to α,β-unsaturated enones afforded the corresponding Micha

A general organocatalytic enantioselective malonate addition to α,β-unsaturated enones

Wascholowski, Veit,Knudsen, Kristian Rahbek,Mitchell, Claire E. T.,Ley, Steven V.

experimental part, p. 6155 - 6165 (2009/05/27)

A general enantioselective organocatalytic conjugate addition procedure of a variety of malonates to α,β-unsaturated enone systems is presented. The reaction is efficiently catalysed by the pyrrolidinyl tetrazole catalyst 1. Cyclic, acyclic and aromatic e
