Check Digit Verification of cas no

The CAS Registry Mumber 1421841-89-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,8,4 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1421841-89:
(9*1)+(8*4)+(7*2)+(6*1)+(5*8)+(4*4)+(3*1)+(2*8)+(1*9)=145
145 % 10 = 5
So 1421841-89-5 is a valid CAS Registry Number.

Extending the utility of [Pd(NHC)(cinnamyl)Cl] precatalysts: Direct arylation of heterocycles

Martin, Anthony R.,Chartoire, Anthony,Slawin, Alexandra M.Z.,Nolan, Steven P.

supporting information, p. 1637 - 1643 (2012/11/07)

The use of [Pd(NHC)(cinnamyl)Cl] precatalysts in the direct arylation of heterocycles has been investigated. Among four different precatalysts, [Pd(SIPr)(cinnamyl)Cl] proved to be the most efficient promoter of the reaction. The C-H functionalization of sulfuror nitrogen-containing heterocycles has been achieved at low catalyst loadings. These catalyst charges range from 0.1 to 0.01 mol % palladium.
