Check Digit Verification of cas no

The CAS Registry Mumber 21939-23-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,3 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21939-23:
(7*2)+(6*1)+(5*9)+(4*3)+(3*9)+(2*2)+(1*3)=111
111 % 10 = 1
So 21939-23-1 is a valid CAS Registry Number.

Reactivity and Diastereoselectivity of Grignard Reagents towards the Hydrazone Functionality in Toluene Solvent

Alexakis, Alex,Lensen, Nathalie,Tranchier, Jean-Philippe,Mangeney, Pierre

, p. 4563 - 4565 (2007/10/02)

Grignard reagents, in toluene solvent, display a strongly increased reactivity toward the hydrazone functionality.With the chiral synthon 1, a highly diastereoselective addition occurs, through chelation control, whereas with pyrazolines 4 and 9 only the d,l diastereomer is formed, leading to a very short synthesis of 1,3-diphenyl-1,3-diaminopropane (11).
