1606590-66-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1606590-66-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,6,5,9 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1606590-66:
(9*1)+(8*6)+(7*0)+(6*6)+(5*5)+(4*9)+(3*0)+(2*6)+(1*6)=172
172 % 10 = 2
So 1606590-66-2 is a valid CAS Registry Number.

Divergent syntheses of fused β-naphthol and indene scaffolds by rhodium-catalyzed direct and decarbonylative alkyne-benzocyclobutenone couplings

Chen, Peng-Hao,Xu, Tao,Dong, Guangbin

, p. 1674 - 1678 (2014)

A tunable rhodium-catalyzed intramolecular alkyne insertion reaction proceeding through the C-C cleavage of benzocyclobutenones is described. Selective formation of either the direct or decarbonylative insertion product can be controlled by using different catalytic systems. A variety of fused β-naphthol and indene scaffolds were obtained in good yields with high functional group tolerance. This work illustrates a divergent approach to synthesize fused-ring systems by C-C activation/functionalization.
