79121-34-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 79121-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,1,2 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 79121-34:
(7*7)+(6*9)+(5*1)+(4*2)+(3*1)+(2*3)+(1*4)=129
129 % 10 = 9
So 79121-34-9 is a valid CAS Registry Number.

Sulfone Group as a Versatile and Removable Directing Group for Asymmetric Transfer Hydrogenation of Ketones

Clarkson, Guy J.,Vyas, Vijyesh K.,Wills, Martin

, p. 14265 - 14269 (2020/07/04)

The sulfone functional group has a strong capacity to direct the asymmetric transfer hydrogenation (ATH) of ketones in the presence of [(arene)Ru(TsDPEN)H] complexes by adopting a position distal to the η6-arene ring. This preference provides a

Enantioselective synthesis of α-hydroxy thioesters via oxazaborolidine- mediated reduction of α-phenylthio enones

Berenguer, Ramon,Cavero, Marta,Garcia, Jordi,Munoz, Montse

, p. 2183 - 2186 (2007/10/03)

α-Phenylthio-α,β-alkenones (2), readily available by Pd(II)-catalysed coupling of (E)-1 phenylthio-1-tributylstannylhex-1-ene with the corresponding acid chlorides have been treated with borane in the presence of phenylglycine- or proline-derived oxazaborolidines to afford 2-phenylthio-2- alken-1-ols (3) with good to excellent enantioselectivities. Ozonolysis of 3 provides a new and efficient route to chiral α-hydroxy thioesters 4.
