114996-61-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 114996-61-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,9,9 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 114996-61:
(8*1)+(7*1)+(6*4)+(5*9)+(4*9)+(3*6)+(2*6)+(1*1)=151
151 % 10 = 1
So 114996-61-1 is a valid CAS Registry Number.

α-fluoromethyl tryptophans via imino ene reaction
Osipov,Kobel'Kova,Kolomiets,Pumpor,Koksch,Burger
, p. 1287 - 1289 (2001)
A preparative simple synthesis of α-fluoromethyl tryptophans is described. The new method is based on a non-catalytic imine ene reaction of highly electrophilic imines derived from methyl bromodifluoro- and trifluoropyruvate, and 1-sulfonyl-3-methylene in
