Check Digit Verification of cas no

The CAS Registry Mumber 128758-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,5 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 128758-88:
(8*1)+(7*2)+(6*8)+(5*7)+(4*5)+(3*8)+(2*8)+(1*8)=173
173 % 10 = 3
So 128758-88-3 is a valid CAS Registry Number.

Chelation control in the addition of homophthalic anhydride to α-alkoxy imines. Pancratistatin model studies

Clark, Robin D.,Souchet, Michel

, p. 193 - 196 (1990)

Diastereoselectivity in the addition of homophthalic anhydride to the α-alkoxy imine (S)-5 can be increased dramatically (to> 90%) with addition of Lewis acids. This methodology has been applied to the synthesis of a model compound (12) which contains four asymmetric centers with the same relative stereochemistry as pancratistatin (1).
