Check Digit Verification of cas no

The CAS Registry Mumber 145219-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,2,1 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 145219-22:
(8*1)+(7*4)+(6*5)+(5*2)+(4*1)+(3*9)+(2*2)+(1*2)=113
113 % 10 = 3
So 145219-22-3 is a valid CAS Registry Number.

Palladium(0)-catalyzed intramolecular decarboxylative allylation of ortho nitrobenzoic esters

Hossian, Asik,Singha, Shantanu,Jana, Ranjan

supporting information, p. 3934 - 3937 (2014/08/18)

A Pd/Ag bimetallic system has been developed for the decarboxylative allylation of ortho-nitrobenzoic esters in an intramolecular fashion. In contrast to the typical sp2-sp3 cross-coupling approach which requires air and moisture sensitive preformed organometallic reagents, we provide an alternative route to the synthesis of ortho-allyl nitroarenes from the corresponding ortho-nitrobenzoic acid derivatives. The reaction proceeds through a mechanistically distinct decarboxylative metalation pathway. A cooperative reactivity of palladium and silver is crucial for the reaction outcome.
