Check Digit Verification of cas no

The CAS Registry Mumber 20595-82-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,9 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20595-82:
(7*2)+(6*0)+(5*5)+(4*9)+(3*5)+(2*8)+(1*2)=108
108 % 10 = 8
So 20595-82-8 is a valid CAS Registry Number.

Gold(I)-catalyzed tandem oxidative ring-opening/C-C bond cleavage reactions of vinylidenecyclopropanes with secondary amines under an oxygen atmosphere

Lu, Bei-Li,Shi, Min

supporting information; experimental part, p. 9070 - 9075 (2011/09/19)

A Midas touch! Gold(I)-catalyzed tandem oxidative ring-opening/C-C bond cleavage reactions of vinylidenecyclopropanes with a variety of secondary amines proceeded smoothly in toluene or 1,1,2,2-tetrachloroethane (TCE) to give the corresponding amides in moderate to good yields under oxygen atmosphere (see scheme; DCE=1,2-dichloroethane). The scope and limitations as well as the plausible mechanisms have been discussed.
