Check Digit Verification of cas no

The CAS Registry Mumber 1449487-84-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,9,4,8 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1449487-84:
(9*1)+(8*4)+(7*4)+(6*9)+(5*4)+(4*8)+(3*7)+(2*8)+(1*4)=216
216 % 10 = 6
So 1449487-84-6 is a valid CAS Registry Number.

Titanium-mediated reductive cross-coupling reactions of imines with terminal alkynes: An efficient route for the synthesis of stereodefined allylic amines

Mao, Kebin,Fan, Guoqin,Liu, Yuanhong,Li, Shi,You, Xu,Liu, Dan

supporting information, p. 621 - 627 (2013/05/22)

Low-valency titanium species, generated in situ by using Ti(OiPr) 4/2 c-C5H9 MgCl reagent, react with imines to give a titanium-imine complex that can couple with terminal alkynes to provide azatitanacyclopentenes with excellent regioselectivity. Stereo-defined allylic amines are obtained in good yields after hydrolysis or iodonolysis of the corresponding azatitanacyclopentenes. When ethynylcyclopropane is used as the coupling partner to react with imines in this reaction, the initially generated allylic amine undergoes an unexpected 1,3-amino migration on silica gel during the column chromatography.
