Check Digit Verification of cas no

The CAS Registry Mumber 1345622-75-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,5,6,2 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1345622-75:
(9*1)+(8*3)+(7*4)+(6*5)+(5*6)+(4*2)+(3*2)+(2*7)+(1*5)=154
154 % 10 = 4
So 1345622-75-4 is a valid CAS Registry Number.

Iodobenzene catalysed synthesis of spirofurans and benzopyrans by oxidative cyclisation of vinylogous esters

Ngatimin, Marsewi,Frey, Raphael,Andrews, Cecily,Lupton, David W.,Hutt, Oliver E.

, p. 11778 - 11780 (2011/12/15)

Vinylogous esters bearing para or meta methoxy benzyl groups undergo oxidative cyclisation with 5-20 mol% iodobenzene and m-CPBA to give spirofuran or benzopyran containing heterocycles. The reaction allows rapid generation of skeletal complexity in good to excellent yields via a novel oxidative cyclisation.
