Check Digit Verification of cas no

The CAS Registry Mumber 82828-86-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,2 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 82828-86:
(7*8)+(6*2)+(5*8)+(4*2)+(3*8)+(2*8)+(1*6)=162
162 % 10 = 2
So 82828-86-2 is a valid CAS Registry Number.

Atmosphere Dependent Photoreaction of 4-Pyridinecarboxylic Ester in Acidic Methanolic Solutions

Sugiyama, Toru,Kusano, Yukari,Yagi, Kazuya,Ito, Yoko,Sugimori, Akira

, p. 1882 - 1886 (1984)

The UV-irradiation of methyl 4-pyridinecarboxylate (1) in methanol under oxygen in the presence of sulfuric acid brings about methoxylation at the 3-position of the pyridine ring, while under nitrogen methoxylation and hydroxymethylation occur at the 2-position.The change of photoreactions of 1 caused by oxygen can not be explained either by the promotion of intersystem crossing by O2 or by the charge transfer interactions between 1 and O2.
