Check Digit Verification of cas no

The CAS Registry Mumber 78172-06-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,7 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 78172-06:
(7*7)+(6*8)+(5*1)+(4*7)+(3*2)+(2*0)+(1*6)=142
142 % 10 = 2
So 78172-06-2 is a valid CAS Registry Number.

STUDIES ON 3,5-DIOXOPIPERIDINES: NOVEL AND FACILE SYNTHETIC ROUTES TO 3-AMINO-5-HYDROXYPYRIDINE DERIVATIVES

Tamura, Yasumitsu,Fujita, Masanobu,Chen, Ling Ching,Kiyokawa, Hiroshi,Ueno, Kyoji,Kita, Yasuyuki

, p. 871 - 874 (2007/10/02)

Three novel synthetic routes to the title compounds were described.Modified Polonovski reaction of 3-acetamido-1-benzyl-5-oxo-3,4-dehydropiperidine (4) or Semmler-Wolff aromatization of 1-benzyl-3-methoxy-5-oxo-3,4-dehydropiperidine oxime (9) followed by reductive debenzylations gave 3-acetamido-5-hydroxypyridine (6) or 3-acetamido-5-methoxypyridine (11), respectively.Nucleophilic replacement of 3,5-dibromopyridine N-oxide (13) with methoxy and amino groups followed by deoxygenation gave 3-amino-5-methoxypyridine (12).
