408328-19-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 408328-19-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,8,3,2 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 408328-19:
(8*4)+(7*0)+(6*8)+(5*3)+(4*2)+(3*8)+(2*1)+(1*9)=138
138 % 10 = 8
So 408328-19-8 is a valid CAS Registry Number.

Simple preparation of nitroso benzenes and nitro benzenes by oxidation of anilines with H2O2 catalysed with molybdenum salts
Defoin, Albert
, p. 706 - 710 (2004)
Nitroso arenes 2a-k are prepared in 53-80% yield from anilines 1a-k by oxidation with H2O2 catalysed with MoO3/KOH, ammonium molybdate or other molybdenum salts. Further oxidation to nitro arenes 3a,d j in 66-90% is also described.
