Check Digit Verification of cas no

The CAS Registry Mumber 13856-65-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,5 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13856-65:
(7*1)+(6*3)+(5*8)+(4*5)+(3*6)+(2*6)+(1*5)=120
120 % 10 = 0
So 13856-65-0 is a valid CAS Registry Number.

, p. 6126 - 6132 (2018)

Through structural modification of 2-anilinonicotinic acid by isomerization, the ΔpKa between the carboxylic acid and pyridinium NH increased dramatically over the threshold to form zwitterions in the newly designed 4-anilinonicotinic acids. Th
