Check Digit Verification of cas no

The CAS Registry Mumber 33631-05-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,3 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 33631-05:
(7*3)+(6*3)+(5*6)+(4*3)+(3*1)+(2*0)+(1*5)=89
89 % 10 = 9
So 33631-05-9 is a valid CAS Registry Number.

Chemoselective Demethylation of Methoxypyridine

Makino, Kosho,Hasegawa, Yumi,Inoue, Takahide,Araki, Koji,Tabata, Hidetsugu,Oshitari, Tetsuta,Ito, Kiyomi,Natsugari, Hideaki,Takahashi, Hideyo

A chemoselective demethylation method for various methoxypyridine derivatives has been developed. Treatment of 4-methoxypyridine with L-selectride in THF for 2 h at reflux temperature afforded 4-hydroxypyridine in good yield; no reaction to anisole occurred. The utility of our method was demonstrated by the efficient synthesis of the metabolic substances of the antiulcer agent omeprazole. Chemoselective demethylation at the site of 3,5-dimethyl-4-methoxypyridine in the presence of 4-methoxybenzimidazole was achieved.

Improved procedures for preparation of 4-hydroxy- and 2-amemo-4-methoxy-2-aminopyridines
