Check Digit Verification of cas no

The CAS Registry Mumber 1041403-36-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,1,4,0 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1041403-36:
(9*1)+(8*0)+(7*4)+(6*1)+(5*4)+(4*0)+(3*3)+(2*3)+(1*6)=84
84 % 10 = 4
So 1041403-36-4 is a valid CAS Registry Number.

Chiral tridentate P,N,N ligands for highly enantioselective copper-catalyzed propargylic amination with both primary and secondary amines as nucleophiles

Zhang, Cheng,Wang, Ya-Hui,Hu, Xin-Hu,Zheng, Zhuo,Xu, Jie,Hu, Xiang-Ping

supporting information, p. 2854 - 2858 (2013/01/15)

Chiral tridentate P,N,N ligands have been demonstrated to be highly efficient for the coppercatalyzed enantioselective propargylic amination of propargylic acetates with both primary and secondary amines as nucleophiles, affording the corresponding propar

Enantioselective copper-catalyzed propargylic amination

Detz, Remko J.,Delville, Marielle M. E.,Hiemstra, Henk,Van Maarseveen, Jan H.

, p. 3777 - 3780 (2008/12/23)

(Chemical Equation Presented) A proper copper catalyst with a chiral pyridine-2,6-bisoxazoline (pybox) ligand was used to convert a variety of propargylic acetates with aromatic side chains (R = Ar) into their amine counterparts in high yield and with good selectivity (up to 88% ee). The resulting chiral propargylic amines can be elaborated further into P,N ligands (see scheme; DIPEA = diisopropylethylamine).
