Check Digit Verification of cas no

The CAS Registry Mumber 1453105-89-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,3,1,0 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1453105-89:
(9*1)+(8*4)+(7*5)+(6*3)+(5*1)+(4*0)+(3*5)+(2*8)+(1*9)=139
139 % 10 = 9
So 1453105-89-9 is a valid CAS Registry Number.

Diastereoselective copper-catalysed 1,4-addition of Grignard reagents to N-enoyl oxazolidinones

Drusan, Michal,Galestokova, Zuzana,Sebesta, Radovan

, p. 9881 - 9888 (2013/09/02)

Conjugate additions of organometallic reagents to α,β- unsaturated carboxylic acid derivatives give access to numerous β-substituted chiral building blocks. Chiral oxazolidinones serve as useful surrogates of carboxylic function in the asymmetric conjugate addition of Grignard reagents. N-Enoyl oxazolidinones undergo this 1,4-addition with a catalytic amount of copper salt and using either chiral or achiral phosphine ligands. In particular, chiral ferrocenyl phosphane oxazolines proved useful in achieving high diastereoselectivities. The resulting N-acyl oxazolidinones were obtained in good yields and with high diastereoselectivities (up to single diastereomer).
