Check Digit Verification of cas no

The CAS Registry Mumber 181650-66-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,6,5 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 181650-66:
(8*1)+(7*8)+(6*1)+(5*6)+(4*5)+(3*0)+(2*6)+(1*6)=138
138 % 10 = 8
So 181650-66-8 is a valid CAS Registry Number.

New investigation of the reaction of 2-amino-2-oxazolines with isocyanates and isothiocyanates. Evidence of a transposition during the second step

Bosc, Jean-Jacques,Jarry, Christian,Ouhabi, Jamal,Laguerre, Michel,Carpy, Alain

, p. 1341 - 1347 (2007/10/03)

The reaction of some 2-amino-2-oxazolines with isocyanates and arylisothiocyanates yields 3-monosubstituted or 2,3-disubstituted 2-iminooxazolidines depending on the experimental conditions and on the nature of the electrophile reactants. The structures of a mono- and a disubstituted derivative were established by X-ray analysis. The chemical behaviour of the compounds was investigated by molecular and quantum mechanics calculations. An intramolecular transposition during the second step of the reaction was found.
