Check Digit Verification of cas no
The CAS Registry Mumber 131114-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,1 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131114-33:
(8*1)+(7*3)+(6*1)+(5*1)+(4*1)+(3*4)+(2*3)+(1*3)=65
65 % 10 = 5
So 131114-33-5 is a valid CAS Registry Number.

Synthesis and antiallergic activity of novel azaazulene derivatives
Nagahara,Nakano,Mimura,Nakamura,Uchida
, p. 2491 - 2499 (2007/10/02)
Various azaazulene derivatives were synthesized and their antiallergic activity was examined. The structure-activity relationship among various derivatives modified by introducing substituents at the 1-,2-, or 3-position of the azaazulene ring was investi
