Check Digit Verification of cas no

The CAS Registry Mumber 1291103-55-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,1,1,0 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1291103-55:
(9*1)+(8*2)+(7*9)+(6*1)+(5*1)+(4*0)+(3*3)+(2*5)+(1*5)=123
123 % 10 = 3
So 1291103-55-3 is a valid CAS Registry Number.

Copper-catalyzed enantioselective propargylic amination of nonaromatic propargylic esters with amines

Yoshida, Akiko,Hattori, Gaku,Miyake, Yoshihiro,Nishibayashi, Yoshiaki

supporting information; experimental part, p. 2460 - 2463 (2011/07/09)

Chemical equations presented. The enantioselective propargylic amination of propargylic pentafluorobenzoates bearing an alkyl group at the propargylic position with amines in the presence of catalytic amounts of a copper complex and an optically active diphosphine such as BINAP has been found to give the corresponding propargylic amines in good yields with high enantioselectivity.
