Check Digit Verification of cas no
The CAS Registry Mumber 78156-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,5 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78156-40:
(7*7)+(6*8)+(5*1)+(4*5)+(3*6)+(2*4)+(1*0)=148
148 % 10 = 8
So 78156-40-8 is a valid CAS Registry Number.

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).
