Check Digit Verification of cas no

The CAS Registry Mumber 1393533-91-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,3,5,3 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1393533-91:
(9*1)+(8*3)+(7*9)+(6*3)+(5*5)+(4*3)+(3*3)+(2*9)+(1*1)=179
179 % 10 = 9
So 1393533-91-9 is a valid CAS Registry Number.

Lewis acid-triggered selective zincation of chromones, quinolones, and thiochromones: Application to the preparation of natural flavones and isoflavones

Klier, Lydia,Bresser, Tomke,Nigst, Tobias A.,Karaghiosoff, Konstantin,Knochel, Paul

, p. 13584 - 13587 (2012)

A Lewis acid-triggered zincation allows the regioselective metalation of various chromones and quinolones. In the absence of MgCl2, a C(3) zincation is observed, whereas in the presence of MgCl2 or a related Lewis acid, C(2) zincation occurs. Applications to a natural flavone, isoflavone, and quinolone are shown.
