7659-46-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7659-46-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,5 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7659-46:
(6*7)+(5*6)+(4*5)+(3*9)+(2*4)+(1*6)=133
133 % 10 = 3
So 7659-46-3 is a valid CAS Registry Number.

Process for the preparation of 2-halogenopyridinealdehydes and novel 2-halogenopyridinealdehydes

-

, (2008/06/13)

The reaction of cyanoolefins, aminocarbonylolefins or hydroxyiminoolefins with a Vilsmeier reagent leads to 2-halogenopyridines which bear aldehyde groups in the 3 and/or 5 position. These pyridinealdehydes are valuable intermediates for the preparation of pharmaceuticals and crop protection agents.
