Check Digit Verification of cas no

The CAS Registry Mumber 303123-83-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,1,2 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 303123-83:
(8*3)+(7*0)+(6*3)+(5*1)+(4*2)+(3*3)+(2*8)+(1*3)=83
83 % 10 = 3
So 303123-83-3 is a valid CAS Registry Number.

Chiral Acetals as Stereoinductors: Diastereoface Selective Alkylation of Dihydrobenzoxazine-Derived Amide Enolates

Mulzer, Johann,Langer, Oliver,Hiersemann, Martin,Bats, Jan W.,Buschmann, Juergen,Luger, Peter

, p. 6540 - 6546 (2007/10/03)

Novel dihydrobenzoxazine-derived acetals of type 3 have been developed for asymmetric C-alkylations of propionyl amide enolates. High stereoselectivities are obtained for amides 15 and 22 which are rationalized in terms of intramolecular metal chelate formation.
