Check Digit Verification of cas no

The CAS Registry Mumber 902171-52-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,2,1,7 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 902171-52:
(8*9)+(7*0)+(6*2)+(5*1)+(4*7)+(3*1)+(2*5)+(1*2)=132
132 % 10 = 2
So 902171-52-2 is a valid CAS Registry Number.

Synthesis of 1,4-dihydro-2-methyl-4-oxo-nicotinic acid: Ochiai's route failed

Ferlin, Maria Grazia,Di Marco, Valerio B.,Dean, Annalisa

, p. 6222 - 6227 (2007/10/03)

The synthesis of 1,4-dihydro-2-methyl- and 1,4-dihydro-1,2-dimethyl-4-oxo-nicotinic acids was accomplished following a route other than Ochiai's procedure, which yielded the isomer 1,6-dihydro-2-methyl-6-oxo-nicotinic acid ethyl ester, and not the 4-oxo-derivative, as reported. Analytical data confirmed the identity of the two isomer oxo-nicotinic acids. UV-vis and potentiometric preliminary data showed that Al(III) does not form complexes with 1,6-dihydro-2-methyl-6-oxo-nicotinic acid ethyl ester in solution, as expected, but with 1,4-dihydro-2-methyl-4-oxo-nicotinic acid.
