112970-73-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 112970-73-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,9,7 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 112970-73:
(8*1)+(7*1)+(6*2)+(5*9)+(4*7)+(3*0)+(2*7)+(1*3)=117
117 % 10 = 7
So 112970-73-7 is a valid CAS Registry Number.

Palladium-Catalyzed Coupling Reactions of (α-Ethoxyvinyl)trimethylstannane with Vinyl and Aryl Triflates

Kwon, Hyok Boong,McKee, Blain H.,Stille, J. K.

, p. 3114 - 3118 (2007/10/02)

The palladium-catalyzed cross-coupling reaction of vinyl triflates and halides with (α-ethoxyvinyl)trimethylstannane gives high yields of 2-ethoxy 1,3-dienes, which can be hydrolyzed to the corresponding α,β-unsaturated ketones.Aryl triflates undergo an analogous coupling reaction, providing a facile method for replacing the hydroxyl group of a phenol by an acyl group.The use of (α-ethoxyvinyl)trimethylstannane in palladium-catalyzed carbonylative coupling gives rise to vinyl and aryl α-ethoxyvinyl ketones and indirectly to the corresponding α-diketones (which result from their hydrolysis) and glyoxylates (which result from their ozonolysis).
