Check Digit Verification of cas no

The CAS Registry Mumber 52578-37-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,5,7 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 52578-37:
(7*5)+(6*2)+(5*5)+(4*7)+(3*8)+(2*3)+(1*7)=137
137 % 10 = 7
So 52578-37-7 is a valid CAS Registry Number.

4-Hydroxy-2-quinolones 120. Synthesis and structure of ethyl 2-hydroxy-4-oxo-4H-pyrido-[1,2-a]pyrimidine-3-carboxylate

Ukrainets,Bereznyakova,Petyunin,Tugaibei,Rybakov,Chernyshev,Turov

, p. 729 - 739 (2008/03/11)

An improved method for the preparation and purification of ethyl 2-hydroxy-4-oxo-4H-pyrido[1,2-a]-pyrimidine-3-carboxylates is proposed. According to 1H and 13C NMR spectroscopic data the synthesized compounds exist in DMSO solution in the 2-hydroxy-4-oxo form while in the crystal (at least for the case of the unsubstituted derivative) X-ray analysis shows that it occurs in the bipolar 2,4-dioxo form.
