72453-90-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72453-90-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,4,5 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 72453-90:
(7*7)+(6*2)+(5*4)+(4*5)+(3*3)+(2*9)+(1*0)=128
128 % 10 = 8
So 72453-90-8 is a valid CAS Registry Number.

A new, expeditious entry to the benzophenanthrofuran framework by a Pd-catalyzed C- And O-arylation/PIFA-M ediated oxidative coupling sequence

Churruca, Fatima,Sanmartin, Raul,Tellitu, Imanol,Dominguez, Esther

, p. 2481 - 2490 (2005)

The synthesis of a series of 2,3-diarylbenzo[b]furans starting from 1,2-diarylethanones and 1,2-dibromoarenes proceeds by means of both homogeneous and polymer-anchored palladium catalysts. This tandem process can be effectively halted at the C-arylation

A new synthetic strategy for the synthesis of bioactive stilbene dimers. A direct synthesis of amurensin H

Kraus, George A.,Gupta, Vinayak

experimental part, p. 7180 - 7183 (2010/03/03)

2,3-Diarylbenzofurans are efficiently generated by the cyclization of ortho-benzyloxybenzophenones using the hindered phosphazene base P4-t-Bu.
