1443674-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1443674-21-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,6,7 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1443674-21:
(9*1)+(8*4)+(7*4)+(6*3)+(5*6)+(4*7)+(3*4)+(2*2)+(1*1)=162
162 % 10 = 2
So 1443674-21-2 is a valid CAS Registry Number.

Enantioselective fluoride ring opening of aziridines enabled by cooperative Lewis acid catalysis
Kalow, Julia A.,Doyle, Abigail G.
, p. 5702 - 5709 (2013)
The enantioselective ring opening of aziridines using a latent source of HF is described. A combination of two Lewis acids, (salen)Co and an achiral Ti(IV) cocatalyst, provided optimal reactivity and enantioselectivity for the trans β-fluoroamine product.
