57802-90-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57802-90-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,8,0 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 57802-90:
(7*5)+(6*7)+(5*8)+(4*0)+(3*2)+(2*9)+(1*0)=141
141 % 10 = 1
So 57802-90-1 is a valid CAS Registry Number.

New and improved syntheses of arylazoxyeyanides
Wood, William W.,Kremp, Gottfried,Petry, Thomas,Simon, Werner E.J.
, p. 619 - 629 (2007/10/03)
Two new approaches to the synthesis of arylazoxycyanides are reported. The most efficient conditions found involve either oxidation of an azocyanide with hydrogen peroxide/formic acid or nitrene insertion into an arylnitroso derivative using cyanamide and
