1394159-44-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1394159-44-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,4,1,5 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1394159-44:
(9*1)+(8*3)+(7*9)+(6*4)+(5*1)+(4*5)+(3*9)+(2*4)+(1*4)=184
184 % 10 = 4
So 1394159-44-4 is a valid CAS Registry Number.

Iron-catalyzed formation of 2-aminopyridines from diynes and cyanamides
Lane, Timothy K.,D'Souza, Brendan R.,Louie, Janis
, p. 7555 - 7563 (2012/11/07)
Diynes and cyanamides undergo an iron-catalyzed [2 + 2 + 2] cycloaddition to form highly substituted 2-aminopyridines in an atom-efficient manner that is both high yielding and regioselective. This system was also used to cyclize two terminal alkynes and
