52765-18-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52765-18-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,7,6 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 52765-18:
(7*5)+(6*2)+(5*7)+(4*6)+(3*5)+(2*1)+(1*8)=131
131 % 10 = 1
So 52765-18-1 is a valid CAS Registry Number.

Process for preparing o-nitrobenzylketones
-
, (2008/06/13)
o-nitrobenzylketones are prepared by reacting a trans-β-substituted amino-2-nitrostyrene with a lower alkanoyl halide, halo-lower alkanoyl halide, phthalimido-lower alkanoyl halide, benzoyl halide or substituted benzoyl halide, and subsequently hydrolyzing the resulting product to yield the desired o-nitrobenzylketone.
