Check Digit Verification of cas no

The CAS Registry Mumber 90440-45-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,4 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90440-45:
(7*9)+(6*0)+(5*4)+(4*4)+(3*0)+(2*4)+(1*5)=112
112 % 10 = 2
So 90440-45-2 is a valid CAS Registry Number.

Addition d'azlactones ylures d'azomethine potentiels a quelques alcenes electrophiles, en milieu anhydride acetique : obtention de pyrrolines-2 et de pyrroles N-acetyles

Yebdri, Okacha,Texier, Fernand

, p. 195 - 201 (2007/10/02)

Azlactones, potential azomethin-ylids, are prepared in situ acetic anhydride from the corresponding α-amino acid, and their addition to electrophilic alkenes RCH=C(X)(Y) leads to N-acetyl Δ2-pyrroline.If X=Y=CN, the pyrroline eliminates HCN and produces a pyrrole.If R=H (acrylic and methacrylic esters and nitriles) the hydrolytic openchain products are obtained.
