1127955-53-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1127955-53-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,7,9,5 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1127955-53:
(9*1)+(8*1)+(7*2)+(6*7)+(5*9)+(4*5)+(3*5)+(2*5)+(1*3)=166
166 % 10 = 6
So 1127955-53-6 is a valid CAS Registry Number.

Synthesis of benzo[b]furans by palladium-NHC catalyzed ring closure of o-bromobenzyl ketones
Farago, Janos,Kotschy, Andras
experimental part, p. 85 - 90 (2009/06/18)
The palladium-catalyzed ring closure of aryl o-bromobenzyl ketones, easily accessible from aromatic aldehydes and 2- bromobenzyl bromide, provides a straightforward route to 2-aryl- benzofurans. A study of the ring closure revealed that a heterocyclic car
