540798-53-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 540798-53-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,0,7,9 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 540798-53:
(8*5)+(7*4)+(6*0)+(5*7)+(4*9)+(3*8)+(2*5)+(1*3)=176
176 % 10 = 6
So 540798-53-6 is a valid CAS Registry Number.

Catalytic enantioselective fluorination of α-chloro-β-keto esters in the presence of chiral nickel complexes
Kang, Seung Hee,Kim, Dae Young
, p. 2783 - 2786 (2010)
The catalytic enantioselective electrophilic fluorination promoted by chiral nickel complexes is described. The treatment of α-chloro-β- keto esters with Selectfluor under mild reaction conditions afforded the corresponding fluorinated α-chloro-β-keto est
