Check Digit Verification of cas no

The CAS Registry Mumber 220211-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,2,1 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 220211-94:
(8*2)+(7*2)+(6*0)+(5*2)+(4*1)+(3*1)+(2*9)+(1*4)=69
69 % 10 = 9
So 220211-94-9 is a valid CAS Registry Number.

Biarylphosphonite gold(I) complexes as superior catalysts for oxidative cyclization of propynyl arenes into indan-2-ones

Henrion, Guilhem,Chavas, Thomas E. J.,Le Goff, Xavier,Gagosz, Fabien

, p. 6277 - 6282 (2013/07/11)

Striking gold: A series of variously functionalized propynyl arenes was smoothly converted into indan-2-ones by a new gold(I)-catalyzed oxidative cyclization process. [LAu]NTf2 (Tf=trifluoromethanesulfonyl) is a superior catalyst both in terms of yield and kinetics for the present transformation. Copyright
