Check Digit Verification of cas no

The CAS Registry Mumber 1192052-75-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,2,0,5 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1192052-75:
(9*1)+(8*1)+(7*9)+(6*2)+(5*0)+(4*5)+(3*2)+(2*7)+(1*5)=137
137 % 10 = 7
So 1192052-75-7 is a valid CAS Registry Number.

Synthesis of fluorenes via the palladium-catalyzed 5-exo-dig annulation of o-alkynylbiaryls

Chernyak, Natalia,Gevorgyan, Vladimir

experimental part, p. 1101 - 1114 (2009/12/07)

The direct palladium-catalyzed intramolecular hydro arylation of o-alkynylbiaryls proceeded in a highly stereoselective manner producing fluorenes 2, the products of 5-exo-dig cyclization, in excellent yields. The cascade intermolecular arylation, incorpo
