124985-48-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 124985-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,9,8 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 124985-48:
(8*1)+(7*2)+(6*4)+(5*9)+(4*8)+(3*5)+(2*4)+(1*8)=154
154 % 10 = 4
So 124985-48-4 is a valid CAS Registry Number.

Suppression of alkene isomerisation in products from intramolecular Heck reactions by addition of Tl(1) salts

Grigg,Loganathan,Santhakumar,Sridharan,Teasdale

, p. 687 - 690 (1991)

Palladium catalysed cyclisations creating products possessing spiro-, fused- and bridged-rings, and tetrasubstituted carbon centres as mixtures of double bond isomers are modified to give single products in the presence of Tl(1) salts.

THE SYNTHESIS OF SPIROCYCLIC COMPOUNDS BY REGIOSPECIFIC PALLADIUM CATALYSED CYCLISATION REACTIONS

Grigg, Ronald,Sridharan, Visuvanathar,Stevenson, Paul,Sukirthalingam, Sukanthini

, p. 3557 - 3568 (2007/10/02)

Enamides derived from o-iodobenzoic acid and Z-3-bromoacrylic acid undergo regiospecific palladium catalysed exo-trig cyclisation onto a proximate alkene to give spirocyclic products in good to excellent yield.Double bond isomerisation in the product is n
