66448-75-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66448-75-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,4 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 66448-75:
(7*6)+(6*6)+(5*4)+(4*4)+(3*8)+(2*7)+(1*5)=157
157 % 10 = 7
So 66448-75-7 is a valid CAS Registry Number.

A SIMPLE AND CONVENIENT SYNTHESIS OF β-HALOKETONES.
Marx, John N.
, p. 1529 - 1532 (2007/10/02)
A new rapid quantitative method to synthesize β-halo-ketones is described (eqn 2) wich utilizes the reaction of an enone with a tetraalkyl ammonium halide in anhydrous trifluoro acetic acid.The method is especially convenient for the preparation of β-iodoketones.
