Check Digit Verification of cas no

The CAS Registry Mumber 40463-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,4,6 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40463-20:
(7*4)+(6*0)+(5*4)+(4*6)+(3*3)+(2*2)+(1*0)=85
85 % 10 = 5
So 40463-20-5 is a valid CAS Registry Number.

Ru(III)-Catalyzed Cyclization of Arene-Alkene Substrates via Intramolecular Electrophilic Hydroarylation

Youn, So Won,Pastine, Stefan J.,Sames, Dalibor

, p. 581 - 584 (2007/10/03)

(Matrix presented) We herein report that RuCl3/AgOTf has proven to be a hydroarylation catalyst with an efficiency and scope superior to previously known methods. This catalyst demonstrated consistent performance with arene-ene substrates of diverse structural features, providing good to excellent yields of cyclization products (chromanes, tetralins, terpenoids, dihydrocoumarins).
