144462-31-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144462-31-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,6 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144462-31:
(8*1)+(7*4)+(6*4)+(5*4)+(4*6)+(3*2)+(2*3)+(1*1)=117
117 % 10 = 7
So 144462-31-7 is a valid CAS Registry Number.

A novel enantioselective preparation of α-fluoro-β-keto acids
Iwaoka,Murohashi,Sato,Kaneko
, p. 1025 - 1028 (2007/10/02)
A two-step method for the enantioselective preparation of α-fluorinated β-keto acids from 1,3-dioxin-4-ones having l-menthone as the chiral auxiliary at the 2-position is described. The method consists of fluorination of the dioxinones by molecular fluori
