206008-32-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 206008-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,0,0 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 206008-32:
(8*2)+(7*0)+(6*6)+(5*0)+(4*0)+(3*8)+(2*3)+(1*2)=84
84 % 10 = 4
So 206008-32-4 is a valid CAS Registry Number.

Ruthenium(II)-Catalyzed Cycloaddition of 1,6-Diynes with Isocyanates Leading to Bicyclic Pyridones
Yamamoto, Yoshihiko,Takagishi, Hideyuki,Itoh, Kenji
, p. 2117 - 2119 (2001)
(matrix presented) A ruthenium(II) complex possessing a planar Cp* ligand, Cp*Ru(cod)Cl, effectively catalyzed the [2 + 2 + 2] cycloaddition of 1,6-diynes with isocyanates to afford bicyclic pyridones in 58-87% yields.
