Check Digit Verification of cas no
The CAS Registry Mumber 909867-68-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,8,6 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 909867-68:
(8*9)+(7*0)+(6*9)+(5*8)+(4*6)+(3*7)+(2*6)+(1*8)=231
231 % 10 = 1
So 909867-68-1 is a valid CAS Registry Number.

A novel synthesis of 2,3-disubstituted-4-pyridones from 4-methoxypyridine
Kitagawa, Hideo,Kumura, Ko,Atsumi, Kunio
, p. 712 - 713 (2006)
Novel 2,3-disubstituted 4-pyridone derivatives were prepared from 4-methoxypyridine through aldol condensation and isomerization of exo-olefin as key reactions, in fairly good to high yields. Copyright
