Check Digit Verification of cas no

The CAS Registry Mumber 28467-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,4,6 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28467-40:
(7*2)+(6*8)+(5*4)+(4*6)+(3*7)+(2*4)+(1*0)=135
135 % 10 = 5
So 28467-40-5 is a valid CAS Registry Number.

Kinetic resolution of chiral cyclohex-2-enones by rhodium(I)/binap- catalyzed 1,2- and 1,4-additions

Kolb, Andreas,Hirner, Sebastian,Harms, Klaus,Zezschwitz, Paultheo Von

supporting information; experimental part, p. 1978 - 1981 (2012/06/18)

The feasibility of kinetic resolutions of racemic monosubstituted cyclohex-2-enones by Rh/binap-catalyzed reactions was investigated. 1,2-Addition of AlMe3 to the 5-substituted derivatives furnished allylic alcohols in the matched case, while t

Chemistry of Higher Order, Mixed Organocuprates. 5. On the Choice of the Copper(I) Salt for the Formation of R2CuLi

Lipshutz, Bruce H.,Kozlowski, Joseph A.,Wilhelm, Robert S.

, p. 546 - 550 (2007/10/02)

Chemical and spectroscopic studies are presented that have been designed to manifest differences in reagent composition and reactivity between mixtures of CuI/2RLi and CuSCN/2RLi.The results indicate that while both Cu(I) salts are reported to serve as precursors to lower order cuprates R2CuLi, CuSCN may actually be forming a higher order, mixed species R2Cu(SCN)Li2.This would explain the discrepancy in coupling reactions of each solution with similar organic substrates under otherwise identical conditions.The presence of added lithium salts demonstrates that while Li I added to CuSCN/2RLi has essentially no effect, introduction of an equivalent of LiSCN to CuI/2RLi dramatically alters the efficiency of ligand transfer.
