Check Digit Verification of cas no

The CAS Registry Mumber 1010691-58-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,0,6,9 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1010691-58:
(9*1)+(8*0)+(7*1)+(6*0)+(5*6)+(4*9)+(3*1)+(2*5)+(1*8)=103
103 % 10 = 3
So 1010691-58-3 is a valid CAS Registry Number.

C1-symmetric oxazolinyl sulfoximines as ligands in copper-catalyzed asymmetric mukaiyama aldol reactions

Sedelmeier, Joerg,Hammerer, Tim,Bolm, Carsten

supporting information; experimental part, p. 917 - 920 (2009/04/07)

Aryl-bridged C1-symmetric oxazolinyl sulfoximines are applicable in copper-catalyzed asymmetric Mukaiyama aldol reactions with methyl pyruvate. The resulting a-hydroxy esters have been obtained with up to 94% ee in good yields. They contain a quaternary stereogenic center and represent valuable precursors for biologically active molecules.
