Check Digit Verification of cas no

The CAS Registry Mumber 109101-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,1,0 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109101-59:
(8*1)+(7*0)+(6*9)+(5*1)+(4*0)+(3*1)+(2*5)+(1*9)=89
89 % 10 = 9
So 109101-59-9 is a valid CAS Registry Number.

Effect of structure of nucleophile and substrate on the quaternization of heterocyclic amines

Zhuravlev,Verolainen,Voronchikhina

, p. 1025 - 1028 (2010)

The influence of the nature of the quaternizing agent and substrate on the quaternization of heterocyclic amines, derivatives of pyridine, ss-picoline, nicotinamide, pyridoxine, was studied. The synthesized compounds were characterized by IR spectroscopy and elemental analysis. The conclusions were made about the effect of the structure of nucleophile and substrate on the process of quaternization reaction. Pleiades Publishing, Ltd., 2010.
