Check Digit Verification of cas no

The CAS Registry Mumber 1233702-23-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,7,0 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1233702-23:
(9*1)+(8*2)+(7*3)+(6*3)+(5*7)+(4*0)+(3*2)+(2*2)+(1*3)=112
112 % 10 = 2
So 1233702-23-2 is a valid CAS Registry Number.

Gold-catalysed room-temperature cycloisomerisation of alkynes and unactivated enolisable ketones

Davies, Paul W.,Detty-Mambo, Christelle

, p. 2918 - 2922 (2010)

The cycloisomerisation of simple keto-alkynes proceeds at room temperature under the mild conditions of gold catalysis. Bicyclic fused and spiro compounds can be obtained by overall 5-exo and 6-exo carbon-carbon bond-forming cyclisations.
