Check Digit Verification of cas no
The CAS Registry Mumber 109658-38-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,5 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109658-38:
(8*1)+(7*0)+(6*9)+(5*6)+(4*5)+(3*8)+(2*3)+(1*8)=150
150 % 10 = 0
So 109658-38-0 is a valid CAS Registry Number.

SYNTHESIS OF ACID-BASE TRANSFORMATIONS OF 3-AROYL-6-METHYL-2-OXOPYRIDINES
Lepikhin, V. A.,Petrichenko, V. M.,Konshin, M. E.
, p. 1097 - 1099 (2007/10/02)
In hydrolysis of 3-aroyl-6-methyl-2-methoxypyridines, 3-aroyl-6-methyl-2-oxopyridines are formed, which with methyl iodide in an alkaline medium give the corresponding 1-methyl derivatives.
