Check Digit Verification of cas no

The CAS Registry Mumber 20224-83-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,2 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20224-83:
(7*2)+(6*0)+(5*2)+(4*2)+(3*4)+(2*8)+(1*3)=63
63 % 10 = 3
So 20224-83-3 is a valid CAS Registry Number.

Carbon-gold bond formation through [3 + 2] cycloaddition reactions of gold(I) azides and terminal alkynes

Partyka, David V.,Updegraff III, James B.,Zeller, Matthias,Hunter, Allen D.,Gray, Thomas G.

, p. 183 - 186 (2008/10/09)

Carbon-gold bond formation propels a growing number of homogeneous catalyses, but the C-Au bond formation itself is comparatively underinvestigated. Reported here are C-Au bond-forming reactions that result from [3 + 2] cycloaddition of (triphenylphosphine)gold(I) azide to terminal alkynes. The reaction proceeds with the preformed azide complex or, in situ, by reaction of the corresponding gold(I) alkynyl with trimethylsilyl azide in the presence of protic solvents. This metal-mediated cycloaddition is analogous to the Huisgen dipolar addition of azides and alkynes and provides access to new classes of gold-bearing compounds and materials.
