Check Digit Verification of cas no

The CAS Registry Mumber 5562-05-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,6 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5562-05:
(6*5)+(5*5)+(4*6)+(3*2)+(2*0)+(1*5)=90
90 % 10 = 0
So 5562-05-0 is a valid CAS Registry Number.

Aza-Diels-Alder reaction of α,β-unsaturated sulfinylimines derived from α-amino acids with enolethers and enamines

Palacios, Francisco,Vicario, Javier,Aparicio, Domitila

, p. 6747 - 6750 (2008/02/13)

α,β-Unsaturated sulfinylimines derived from α-amino acids undergo aza-Diels-Alder reaction with electron rich dienophiles such as enolethers and enamines. Subsequent elimination of sulfinyl and amine or alkoxy moiety on the resulting cycloadducts affords
