Check Digit Verification of cas no

The CAS Registry Mumber 667419-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,7,4,1 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 667419-56:
(8*6)+(7*6)+(6*7)+(5*4)+(4*1)+(3*9)+(2*5)+(1*6)=199
199 % 10 = 9
So 667419-56-9 is a valid CAS Registry Number.

Substituent effects in the binding of bis(4-fluorobenzyl)ammonium ions by dianilino[24]crown-8

Chiu, Sheng-Hsien,Liao, Kang-Shyang,Su, Jen-Kuan

, p. 213 - 216 (2007/10/03)

A series of para-substituted dianilino[24]crown-8 (DA24C8) macrocycles were synthesized and their ability to form host-guest complexes with bis(4-fluorobenzyl)ammonium ions (DFA+) were investigated. Although these crown ethers contain weakly hy
