Calculate Digit Verification of CAS Registry Number 80478-55:
(7*8)+(6*0)+(5*4)+(4*7)+(3*8)+(2*5)+(1*5)=143
143 % 10 = 3
So 80478-55-3 is a valid CAS Registry Number.

Photoreaction of N,N'-Dibromo-2,5-piperazinedione

Sera, Akira,Itoh, Kuniaki,Yamada, Hiroshi,Aoki, Ryuichi

, p. 3453 - 3455 (2007/10/02)

The photolysis of N,N'-dibromo-2,5-piperazinedione in dichloromethane gave an unstable photoproduct.The alcoholysis of the photoproduct in the presence of a small amount of hydrogen bromide yielded 3,6-diethoxy-2,5-piperazinedione and its alcoholyzed products, ethyl diethoxyacetate, ethyl 2-(diethoxyacetylamino)-2-ethoxyacetate, N-(1-ethoxy-1-ethoxycarbonylmethyl)oxamide, and ethyl N-(diethoxyacetyl)glycinate.The reactions of the photoproduct with other nucleophiles also gave the corresponding substituted 2,5-piperazinediones.The structure of the primary photoproduct was deduced to be 3,6-dibromo-2,5-piperazinedione on the basis of these observations.
