Check Digit Verification of cas no

The CAS Registry Mumber 1221406-67-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,4,0 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1221406-67:
(9*1)+(8*2)+(7*2)+(6*1)+(5*4)+(4*0)+(3*6)+(2*6)+(1*7)=102
102 % 10 = 2
So 1221406-67-2 is a valid CAS Registry Number.

Intermolecular dehydrative coupling reaction of aryl ketones with cyclic alkenes catalyzed by a well-defined cationic ruthenium-hydride complex: A novel ketone olefination method via vinyl C-H bond activation

Yi, Chae S.,Lee, Do W.

, p. 1883 - 1885 (2010)

The cationic ruthenium-hydride complex [(η6-C 6H6)(PCy3)(CO)RuH]+BF 4- was found to be a highly effective catalyst for the intermolecular olefination reaction of aryl ketones with cycloalkenes. The preliminary mechanistic analysis revealed that an electrophilic ruthenium-vinyl complex is the key species for mediating both vinyl C-H bond activation and the dehydrative olefination steps of the coupling reaction.
