Check Digit Verification of cas no

The CAS Registry Mumber 1374003-10-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,0,0 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1374003-10:
(9*1)+(8*3)+(7*7)+(6*4)+(5*0)+(4*0)+(3*3)+(2*1)+(1*0)=117
117 % 10 = 7
So 1374003-10-7 is a valid CAS Registry Number.

Copper bis(oxazolines) as catalysts for stereoselective aziridination of styrenes with N-tosyloxycarbamates

Lebel, Hélne,Parmentier, Micha?l,Leogane, Olivier,Ross, Karen,Spitz, Cédric

, p. 3396 - 3409 (2012/06/15)

A Cu(I)-catalyzed asymmetric aziridination of styrenes with a chiral N-tosyloxycarbamate has been developed. Double stereodifferentiation was observed and both the N-tosyloxycarbamate substituent and the bis(oxazoline) ligand have a significant effect on the yields and diastereoselectivities. The best results for the aziridination were obtained with electron-deficient styrenes. Subsequent ring-opening reactions of styrene-derived aziridines at the benzylic position were observed with various oxygen and nitrogen nucleophiles under Lewis acid catalysis affording the corresponding products with complete inversion of stereochemistry. The strategy was used to synthesize the β-blocker, (R)-nifenalol.
