Check Digit Verification of cas no
The CAS Registry Mumber 111974-39-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,9,7 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 111974-39:
(8*1)+(7*1)+(6*1)+(5*9)+(4*7)+(3*4)+(2*3)+(1*9)=121
121 % 10 = 1
So 111974-39-1 is a valid CAS Registry Number.

An Easy and Convenient Synthesis of 6-Methyl-4(1H)-pyridone-3-carboxylic Acid
Mittelbach, Martin
, p. 479 - 480 (1988)
A new and easy synthesis of 6-methyl-4(1H)-pyridone-3-carboxylic acid (5), an important component of broad spectrum cephalosporins, is described.It starts from the readily available ethyl 4-hydroxy-6-methyl-2(1H)-pyridone-3-carboxylate (1), which is treated with phosphoryl chloride to give ethyl 2,4-dichloro-6-methylpyridine-3-carboxylate (2).Selective substitution of the chlorine in 4-position with alkoxide ion leads to the 4-alkoxypyridine derivatives 3.Hydrogenolysis of 3 affords ethyl 4-alkoxy-6-methyl-pyridine-3-carboxylates 4; which are hydrolysed to 5 in one step.
