142892-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142892-53-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,8,9 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142892-53:
(8*1)+(7*4)+(6*2)+(5*8)+(4*9)+(3*2)+(2*5)+(1*3)=143
143 % 10 = 3
So 142892-53-3 is a valid CAS Registry Number.

High π-route reactivity in the tropene system. Absence of a nitrogen acceleration effect
Murr, Brown L.,Parkhill, Billy J.,Nickon, Alex
, p. 4845 - 4862 (2007/10/02)
Solvolyses of a suitably constructed tropene tosylate and its unsaturated carbocyclic analog show that the amino function, despite its suitable spatial location, does not enhance the π-route assistance but reduces it slightly.
