497161-84-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 497161-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,1,6 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 497161-84:
(8*4)+(7*9)+(6*7)+(5*1)+(4*6)+(3*1)+(2*8)+(1*4)=189
189 % 10 = 9
So 497161-84-9 is a valid CAS Registry Number.

Highly enantioselective inverse-electron-demand hetero-Diels-Alder reactions of α,β-unsaturated aldehydes

Gademann, Karl,Chavez, David E.,Jacobsen, Eric N.

, p. 3059 - 3061 (2007/10/03)

Straightforward access to useful synthetic intermediates is provided by this new method. Simple, α,β-unsaturated aldehydes are excellent substrates in the hetero-Diels-Alder reaction with inverse electron demand, catalyzed by CrIII-Schiff base complexes (see scheme; R1, R2 = alkyl or aryl) in the presence of 4-A molecular sieves and no solvent. The resulting dihydropyrans are obtained in high enantio- (89-98 % ee) and diastereoselectivity (> 95 % de) and yield (40-95 %).
