Check Digit Verification of cas no

The CAS Registry Mumber 174692-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,6,9 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 174692-90:
(8*1)+(7*7)+(6*4)+(5*6)+(4*9)+(3*2)+(2*9)+(1*0)=171
171 % 10 = 1
So 174692-90-1 is a valid CAS Registry Number.

Oxindole alkaloids. A novel non-biomimetic entry to (-)-horsfiline

Palmisano, Giovanni,Annunziata, Rita,Papeo, Gianluca,Sisti, Massimo

, p. 1 - 4 (2007/10/03)

A novel non-biomimetic synthesis of horsfiline has been developed. The key pyrrolidine forming reaction is the 1,3-dipolar cycloaddition of the thermally generated N-methylazomethine ylide to a suitable 3-akylidene-indolin-2(3H)one. The same strategy was also applied to the synthesis of pure (R)-(-)-enantiomer.
