Check Digit Verification of cas no

The CAS Registry Mumber 1047997-53-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,7,9,9 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1047997-53:
(9*1)+(8*0)+(7*4)+(6*7)+(5*9)+(4*9)+(3*7)+(2*5)+(1*3)=194
194 % 10 = 4
So 1047997-53-4 is a valid CAS Registry Number.

Substituted benzocarbocycles by palladium-catalyzed cascade reactions featuring a C(sp3) - H activation step

Hitce, Julien,Baudoin, Olivier

, p. 2054 - 2060 (2008/09/17)

Valuable 4- and 5-membered benzocarbocycles were synthesized via selective palladium-catalyzed cascade reactions which combined C(sp3)-H activation, Heck cyclization, Heck arylation or olefin hydrogenation. In all cases, all mechanistically independent steps were catalyzed by a single multi-functional catalyst.
