Check Digit Verification of cas no

The CAS Registry Mumber 57724-34-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,7,2 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 57724-34:
(7*5)+(6*7)+(5*7)+(4*2)+(3*4)+(2*3)+(1*4)=142
142 % 10 = 2
So 57724-34-2 is a valid CAS Registry Number.

One pot domino reaction accessing γ-nitroesters: Synthesis of GABA derivatives

Naciuk, Fabricio F.,Vargas, Debora Z.,D'oca, Caroline R. M.,Moro, Celso C.,Russowsky, Dennis

, p. 1643 - 1653 (2015)

Michael addition of 1,3-dicarbonyl compounds to nitrostyrenes is efficiently promoted by hydrotalcite [Mg-Al] to afford the respective γ-nitrodicarbonyl adducts. Differently, the addition of Meldrum's acid leads to a direct access of γ-nitroesters through a one pot domino process. GABA derivatives (+/-)-phenibut and (+/-)-baclofen were readily synthesized from the respective nitro adducts.
