Check Digit Verification of cas no

The CAS Registry Mumber 1256093-82-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,0,9 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1256093-82:
(9*1)+(8*2)+(7*5)+(6*6)+(5*0)+(4*9)+(3*3)+(2*8)+(1*2)=159
159 % 10 = 9
So 1256093-82-9 is a valid CAS Registry Number.

Enantioselective nickel-catalyzed reductive coupling of alkynes and imines

Zhou, Chang-Yue,Zhu, Shou-Fei,Wang, Li-Xin,Zhou, Qi-Lin

supporting information; experimental part, p. 10955 - 10957 (2010/09/17)

The nickel-catalyzed reductive coupling of alkynes and imines with Et 2Zn as a reductant by using electron-rich phosphine ligands has been developed, affording various allylic amines with high yields and excellent chemoselectivities. Chiral induction was also achieved in this reductive coupling reaction when a nickel catalyst containing a chiral spiro phosphine ligand was used.
