Check Digit Verification of cas no
The CAS Registry Mumber 81067-44-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,6 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81067-44:
(7*8)+(6*1)+(5*0)+(4*6)+(3*7)+(2*4)+(1*4)=119
119 % 10 = 9
So 81067-44-9 is a valid CAS Registry Number.

Palladium-catalyzed aryl amination-heck cyclization cascade: A one-flask approach to 3-substituted indoles
Jensen, Thomas,Pedersen, Henrik,Bang-Andersen, Benny,Madsen, Robert,Jorgensen, Morten
, p. 888 - 890 (2008)
(Chemical Equation Presented) Two for the price of one: A Pd/dppf-based catalyst provides access to the title compounds from 1,2-dihalogenated aromatic compounds and allylic amines in a single reaction flask. The initial aryl amination step occurs with excellent selectivity for the aryl iodide to ensure the formation of a single indole regioisomer, which can be functionalized in situ by N-arylation (see scheme). dba = dibenzylideneacetone, dppf = 1,1′-bis(diphenylphospanyl)ferrocene.
