Check Digit Verification of cas no

The CAS Registry Mumber 130798-47-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,9 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130798-47:
(8*1)+(7*3)+(6*0)+(5*7)+(4*9)+(3*8)+(2*4)+(1*7)=139
139 % 10 = 9
So 130798-47-9 is a valid CAS Registry Number.

Ligand-accelerated enantioselective propargylation of aldehydes via allenylzinc reagents

Trost, Barry M.,Ngai, Ming-Yu,Dong, Guangbin

supporting information; experimental part, p. 1900 - 1903 (2011/06/21)

An enantioselective propargylation of aldehydes using an allenylzinc reagent generated in situ via a zinc-iodine exchange reaction is described. The enantioselectivity is controlled by addition of a catalytic amount of readily accessible and highly tunable amino alcohol ligand L13. A wide range of aldehydes can be propargylated to afford valuable and versatile homopropargyl alcohols in good to excellent yields with high levels of enantiopurity.
