Check Digit Verification of cas no

The CAS Registry Mumber 190083-64-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,0,8 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 190083-64:
(8*1)+(7*9)+(6*0)+(5*0)+(4*8)+(3*3)+(2*6)+(1*4)=128
128 % 10 = 8
So 190083-64-8 is a valid CAS Registry Number.

Bis(oxazoline) and bis(oxazolinyl)pyridine copper complexes as enantioselective Diels-Alder catalysts: Reaction scope and synthetic applications

Evans, David A.,Barnes, David M.,Johnson, Jeffrey S.,Lectka, Thomas,Von Matt, Peter,Miller, Scott J.,Murry, Jerry A.,Norcross, Roger D.,Shaughnessy, Eileen A.,Campos, Kevin R.

, p. 7582 - 7594 (2007/10/03)

The scope of the Diels-Alder reaction catalyzed by bis(oxazoline) copper complexes has been investigated. In particular, [Cu((S,S)-t-Bu-box)](SbF6)2 (1b) has been shown to catalyze the Diels-Alder reaction between 3-propenoyl- 2-oxaz
