91476-30-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91476-30-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,4,7 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91476-30:
(7*9)+(6*1)+(5*4)+(4*7)+(3*6)+(2*3)+(1*0)=141
141 % 10 = 1
So 91476-30-1 is a valid CAS Registry Number.

ADDITION OF FUNCTIONALIZED ALLYLIC BROMIDES TO TERMINAL ALKYNES

Knochel, P.,Normant, J. F.

, p. 1475 - 1478 (1984)

Bromoesters 2a, 2b and bromophosphonates 2c, 2d add regioselectively to terminal alkynes in the presence of zinc to give the highly functionnalized dienes 4-7 which are cyclized to various six or seven membered carbo- or heterocycles.

SYNTHESE DE DIENES-1,4 FONCTIONNALISES PAR ADDITION DE ZINCIQUES ALLYLIQUES FONCTIONNALISES SUR DES ALCYNES VRAIS ET LEUR CYCLISATION EN HETEROCYCLES OU CARBOCYCLES

Knochel, P.,Normant, J. F.

, p. 1 - 24 (2007/10/02)

The regiospecific addition of functionalized allylic bromides to terminal alkynes in the presence of zinc furnishes a great variety of highly functionalized 1,4-dienes with moderate to good yields.The synthetic utility of these 1,4-dienes is demonstrated by various cyclization reactions leading to an α-methylene-γ-butyrolactone, to 3,5-difunctionalized piperidines, to a cyclic triester and to 6- or 7-membered phosphorus heterocyclic compounds.
