Check Digit Verification of cas no
The CAS Registry Mumber 31557-75-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,5 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 31557-75:
(7*3)+(6*1)+(5*5)+(4*5)+(3*7)+(2*7)+(1*5)=112
112 % 10 = 2
So 31557-75-2 is a valid CAS Registry Number.

Nitropyridines: X.* Palladium-catalyzed cross-coupling of 2-bromo-5-nitropyridine with terminal acetylenes
Sagitullina,Vorontsova,Garkushenko,Poendaev,Sagitullin
experimental part, p. 1830 - 1834 (2011/04/15)
Substituted 5-nitro-2-ethynylpyridines were synthesized by the Sonogashira reaction of 2-bromo-5-5-nitropyridine with terminal acetylenes. Desilylation, oxidative decarbonylation, and the retro-Favorskii reaction of the cross-coupling products of 2-bromo-5-nitropyridine with trimethylsilylacetylene, prop-2-ynyl alcohol, and 2-methylbut-3-yn-2-ol, respectively, gave 2-ethynyl-5-nitropyridine. The hydration of 2-ethynyl-5-nitropyridine and 5-nitro-2-(phenylethynyl)pyridine according to Kucherov afforded 2-acetyl-5-nitropyridine and 5-nitro-2-phenacylpyridine, respectively.
