Calculate Digit Verification of CAS Registry Number 250722-19:
(8*2)+(7*5)+(6*0)+(5*7)+(4*2)+(3*2)+(2*1)+(1*9)=111
111 % 10 = 1
So 250722-19-1 is a valid CAS Registry Number.

Direct conversion of aldehydes into nitriles via O-phenylcarbamoylated aldoximes

Coskun, Necdet,Arikan, Nevin

, p. 11943 - 11948 (1999)

O-Arylcarbamoylated hydroxylamine tosylate reacts with aldehydes at room temperature to give the corresponding O-carbamoylated oximes. The reaction of carbamoylated hydroxylamine with aromatic aldehydes in THF or in toluene at reflux affords the corresponding nitriles and anilinium tosylate in high yield. Attempts to cyclize compounds 2 in the presence of AcCl lead again to the formation of nitriles.
