Check Digit Verification of cas no

The CAS Registry Mumber 198223-93-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,2,2 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 198223-93:
(8*1)+(7*9)+(6*8)+(5*2)+(4*2)+(3*3)+(2*9)+(1*3)=167
167 % 10 = 7
So 198223-93-7 is a valid CAS Registry Number.

Enantioselective Diels-Alder reactions: Novel constrained bis(oxazoline) ligand-metal triflate catalysts

Takacs, James M.,Quincy, David A.,Shay, William,Jones, Brian E.,Ross II, Charles R.

, p. 3079 - 3087 (2007/10/03)

Five chiral 1,4-bis(oxazoline) ligands, each bearing a bicyclic backbone, were prepared and examined in Mg(OTf)2-, Zn(OTf)2, and Cu(OTf)2 catalyzed Diels-Alder reactions. The cycloadditions were carried out at room tempera
