Check Digit Verification of cas no

The CAS Registry Mumber 1380484-82-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,0,4,8 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1380484-82:
(9*1)+(8*3)+(7*8)+(6*0)+(5*4)+(4*8)+(3*4)+(2*8)+(1*2)=171
171 % 10 = 1
So 1380484-82-1 is a valid CAS Registry Number.

Highly diastereo- and enantioselective Cu-catalyzed [3 + 3] cycloaddition of propargyl esters with cyclic enamines toward chiral bicyclo[n.3.1] frameworks

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

, p. 9585 - 9588 (2012)

A new Cu-catalyzed asymmetric [3 + 3] cycloaddition of propargyl esters with cyclic enamines is reported. With a combination of Cu(OAc) 2·H2O and a chiral tridentate ferrocenyl-P,N,N ligand as the catalyst, perfect endo selectivities (endo/exo > 98/2) and excellent enantioselectivities (up to 98% ee) for endo cycloadducts were achieved under mild conditions. This method provides a simple and efficient approach for the synthesis of optically active bicyclo[n.3.1] frameworks.
