Check Digit Verification of cas no

The CAS Registry Mumber 190004-42-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,0,0 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 190004-42:
(8*1)+(7*9)+(6*0)+(5*0)+(4*0)+(3*4)+(2*4)+(1*2)=93
93 % 10 = 3
So 190004-42-3 is a valid CAS Registry Number.

Stereoselectivity in the amination of chiral cyclohex-3-en-1-one ketals

Fioravanti, Stefania,Luna, Giuseppe,Pellacani, Lucio,Tardella, Paolo A.

, p. 4779 - 4786 (1997)

Optically active cyclohex-3-en-1-one ketals by photolysis of N3CO2-Et or N3C(OEt)NMs or by CaO induced α-elimination of NsONHCO2Et give diastereomeric aziridines (up to 72% yields, up to 60% d.e.). A simple HPLC separation allows to obtain practically pure aziridines. The conversion of the main product to the ketal of (R)-N-(ethoxycarbonyl)-β-aminocyclohexanone is also reported and a further oxidation directly gives a derivative of (R)-2-aminoadipic acid.
