Calculate Digit Verification of CAS Registry Number 57767-04:
(7*5)+(6*7)+(5*7)+(4*6)+(3*7)+(2*0)+(1*4)=161
161 % 10 = 1
So 57767-04-1 is a valid CAS Registry Number.

, p. 1402 - 1405 (2007/10/02)

In the reactions of N-monosubstituted p-nitrobenzamide oximes with orthoformic ester in presence of boron trifluoride ether complex p-nitrobenzonitrile and a carbamate of the original amide oxime are formed.Under the same condition bis(methylamino)glyoxime gives a 1-cyano-N-methylformamide oxime carbamate.
