The CAS Registry Mumber 77778-41-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,7 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77778-41:
(7*7)+(6*7)+(5*7)+(4*7)+(3*8)+(2*4)+(1*1)=187
187 % 10 = 7
So 77778-41-7 is a valid CAS Registry Number.

Reductive Debromination and Coupling Reaction in the Thermolysis of 5-Bromouracils in N,N-Dialkylamides. Cleavage of the C(5)-Bromine bond by an Initial Electron-transfer Process

Sako, Magiochi,Suzuki, Mikio,Tanabe, Miyuki,Maki, Yoshifumi

, p. 3114 - 3117 (2007/10/02)

Thermolysis of various 5-bromouracils (1) in N,N-dialkylamides results in the formation of methylenebisuracils (2) and reductive debrominated products (3) via cleavage of the C(5)-Br bond; the latter involves a one-electron transfer process.The product distribution between (2) and (3) depends upon the nature of substituents in the uracil ring.
