Check Digit Verification of cas no

The CAS Registry Mumber 1013936-27-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,3,9,3 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1013936-27:
(9*1)+(8*0)+(7*1)+(6*3)+(5*9)+(4*3)+(3*6)+(2*2)+(1*7)=120
120 % 10 = 0
So 1013936-27-0 is a valid CAS Registry Number.

Ruthenium-catalyzed vinylic substitution reactions with nucleophiles via butatrienylidene intermediates

, p. 2908 - 2909 (2008/10/09)

Novel ruthenium-catalyzed vinylic substitution reactions of vinylic trifluoromethanesulfonates with nucleophiles such as cyclic 1,3-diketones and alcohols have been found to give the corresponding vinylic-substituted products in good to high yields. This catalytic reaction is considered to be a new type of vinylic substitution reaction. Reactions of α-ketoacetylenes with alcohols have also been found to afford the corresponding vinylic ethers in good yields. These catalytic reactions can be explained to proceed by proposing ruthenium-butatrienylidene complexes as key intermediates. We believe that this finding will open up a further aspect of the chemistry of metal-cumulenylidene complexes. Copyright
