142839-58-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142839-58-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,8,3 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 142839-58:
(8*1)+(7*4)+(6*2)+(5*8)+(4*3)+(3*9)+(2*5)+(1*8)=145
145 % 10 = 5
So 142839-58-5 is a valid CAS Registry Number.

Enantioselective Cation Binding with a Functionalized Podand Ionophore
Armstrong, Alan,Still, W. Clark
, p. 4580 - 4582 (2007/10/02)
By adding an acetamido group to podand 1, a new ionophore 2 is created which binds peptidic ammonium ions with high enantioselectivity.
