Check Digit Verification of cas no

The CAS Registry Mumber 925417-22-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,5,4,1 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 925417-22:
(8*9)+(7*2)+(6*5)+(5*4)+(4*1)+(3*7)+(2*2)+(1*2)=167
167 % 10 = 7
So 925417-22-7 is a valid CAS Registry Number.

One-pot synthesis of imidazolines from aldehydes: detailed study about solvents and substrates

Fujioka, Hiromichi,Murai, Kenichi,Kubo, Ozora,Ohba, Yusuke,Kita, Yasuyuki

, p. 638 - 643 (2007/10/03)

Imidazolines were prepared in one-pot operation from aldehydes and diamines through oxidation of aminal intermediates by NBS. This method could be applied to various aromatic and aliphatic aldehydes and N-nonsubstituted and N-monosubstituted 1,2-diamines. Furthermore, it was found that CH2Cl2 could be altered to TBME, a more environmentally friendly solvent, in the reaction using N-nonsubstituted 1,2-diamines. The reaction conditions were very mild and chemoselective.
