607405-74-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 607405-74-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,0,7,4,0 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 607405-74:
(8*6)+(7*0)+(6*7)+(5*4)+(4*0)+(3*5)+(2*7)+(1*4)=143
143 % 10 = 3
So 607405-74-3 is a valid CAS Registry Number.

Alkali metal counterion control of enolate protonation stereoselectivity

Hu, Yang,Bishop, Raynauld L.,Luxenburger, Andreas,Dong, Shuzhi,Paquette, Leo A.

, p. 2735 - 2737 (2006)

Generation of the lithium salt of the norbornenol shown (M = H) followed by quenching with aqueous NH4Cl solution gives predominantly the β-epimeric ketone 6. Similar production of the potassium alkoxide leads instead to the α-epimer (99:1). Th

Total synthesis of dumsin. 1. Retrosynthetic strategy and the elaboration of key intermediates from (-)-bornyl acetate

Paquette, Leo A.,Hong, Fang-Tsao

, p. 6905 - 6918 (2007/10/03)

An intramolecular anionic oxy-Cope rearrangement (44 → 46) serves as the key step in a synthetic approach to the insect antifeedant dumsin. Initial investigations clarified the manner in which (-)-bornyl acetate may be transformed into the exo-norbornenol
