Check Digit Verification of cas no

The CAS Registry Mumber 1239456-70-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,4,5 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1239456-70:
(9*1)+(8*2)+(7*3)+(6*9)+(5*4)+(4*5)+(3*6)+(2*7)+(1*0)=172
172 % 10 = 2
So 1239456-70-2 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.
