Check Digit Verification of cas no

The CAS Registry Mumber 134138-88-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,1,3 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134138-88:
(8*1)+(7*3)+(6*4)+(5*1)+(4*3)+(3*8)+(2*8)+(1*8)=118
118 % 10 = 8
So 134138-88-8 is a valid CAS Registry Number.

Development of a Novel Series of (2-Quinolinylmethoxy)phenyl-Containing Compounds as High-Affinity Leukotriene D4 Receptor Antagonists. 4. Addition of Chromone Moiety Enhances Leukotriene D4 Receptor Binding Affinity

Huang, Fu-Chih,Galemmo, Robert A.,Poli, Gregory B.,Learn, Keith S.,Morrissette, Mathew M.,et al.

, p. 1704 - 1707 (1991)

The combination of the benzopyran-4-one ring, a moiety found in the prototype leukotriene antagonist, FPL 55,712, with the (2-quinolinylmethoxy)phenyl group led to a significant increase in leukotriene receptor binding affinity.This modification resulted
