Check Digit Verification of cas no

The CAS Registry Mumber 861389-38-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,3,8 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 861389-38:
(8*8)+(7*6)+(6*1)+(5*3)+(4*8)+(3*9)+(2*3)+(1*8)=200
200 % 10 = 0
So 861389-38-0 is a valid CAS Registry Number.

Palladium-catalyzed sequential alkylation-alkenylation reactions: Application towards the synthesis of polyfunctionalized fused aromatic rings

Alberico, Dino,Paquin, Jean-Fran?ois,Lautens, Mark

, p. 6283 - 6297 (2005)

The synthesis of polyfunctionalized fused aromatic carbo- and heterocycles from aryl iodides and bromoenoates via a tandem palladium-catalyzed aromatic substitution intramolecular Heck sequence is reported. Using Pd(OAc)2 and tri-2-furylphosphine (TFP) in the presence of norbornene and Cs 2CO3 in CH3CN at 85°C gave a variety of functionalized bi- and tricyclic fused aromatic rings in good yield.
