69955-03-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69955-03-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,5 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 69955-03:
(7*6)+(6*9)+(5*9)+(4*5)+(3*5)+(2*0)+(1*3)=179
179 % 10 = 9
So 69955-03-9 is a valid CAS Registry Number.

Process for preparing fluorinated amino-nitriles
-
, (2008/06/13)
Certain α-(fluoromethyl or difluoromethyl)-α-aminoacetonitriles are prepared by treating the appropriate α-(fluoromethyl or difluoromethyl) ketimine magnesium halide with hydrogen cyanide or with an alkali metal cyanide or ammonium cyanide and a proton source. The products are useful as intermediates for making α-(fluoromethyl or difluoromethyl)-α-amino acids having pharmacological activity.
