Check Digit Verification of cas no

The CAS Registry Mumber 412021-24-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,2,0,2 and 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 412021-24:
(8*4)+(7*1)+(6*2)+(5*0)+(4*2)+(3*1)+(2*2)+(1*4)=70
70 % 10 = 0
So 412021-24-0 is a valid CAS Registry Number.

Asymmetric Michael addition of chiral lithiated sulfonates to nitroalkenes: Diastereo- and enantioselective synthesis of α,β-disubstituted γ-nitro and β-alkoxycarbonyl methyl sulfonates

Enders, Dieter,Berner, Otto Mathias,Vignola, Nicola,Harnying, Wacharee

, p. 1945 - 1952 (2007/10/03)

The diastereoselective Michael addition of lithiated enantiopure sulfonates to nitroalkenes is described. High asymmetric inductions were obtained by using 1,2:5,6-di-O-isopropylidene-α-D-allofuranose as a cheap and easily available chiral auxiliary. Race
