868-47-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 868-47-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,6 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 868-47:
(5*8)+(4*6)+(3*8)+(2*4)+(1*7)=103
103 % 10 = 3
So 868-47-3 is a valid CAS Registry Number.

N-bonded enolatorhenium(I) complexes having dimethylphenylphosphine ligands as active key intermediates in catalytic Knoevenagel and Michael reactions

, p. 3 - 14 (1998)

Enolatorhenium(I) complexes cis-Re(NCCRCO2R′)(NCCHRCO2R′)(PMe 2Ph)4 (R=H, R′=Me (2a); R=H, R′=Et (2b); R=H, R′=n-Bu (2c); R=Me, R′=Et (2d)) are prepared by the reaction of ReH(N2)(PMe2Ph)4 (1) with alkyl cyanoalkyl carboxylate. X-ray structure analysis of 2b shows that it has an octahedral Re geometry, where mutually cis enolato and ester ligands bind to the rhenium via cyano groups. Reaction of 2b with benzaldehyde gives Re(NCCHCO2Et)[NC(EtO2C)C=CHPh]-(PMe2Ph) 4 (4), which is also derived from the ligand exchange reaction of 2b with ethyl (E)-2-cyano-3-phenylpropenoate. These rhenium(I) complexes 1, 2, and 4 catalyze Knoevenagel and Michael reactions under neutral and mild conditions. A possible mechanism for the Knoevenagel reaction has been proposed.
