Check Digit Verification of cas no

The CAS Registry Mumber 28749-99-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,7,4 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 28749-99:
(7*2)+(6*8)+(5*7)+(4*4)+(3*9)+(2*9)+(1*9)=167
167 % 10 = 7
So 28749-99-7 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 (2004)

(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).
