Check Digit Verification of cas no

The CAS Registry Mumber 749898-29-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,9,8,9 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 749898-29:
(8*7)+(7*4)+(6*9)+(5*8)+(4*9)+(3*8)+(2*2)+(1*9)=251
251 % 10 = 1
So 749898-29-1 is a valid CAS Registry Number.

An evaluation of some hindered diamines as chiral modifiers of metal-promoted reactions

Illesinghe, Jayamini,Ebeling, Richard,Ferguson, Brett,Patel, Jim,Campi, Eva M.,Jackson, W. Roy,Robinson, Andrea J.

, p. 167 - 176 (2007/10/03)

Diamino analogues of the C2-symmetric chiral diphosphine ligands DuPHOS and BPE have been prepared and evaluated as chiral modifiers of the osmium tetraoxide dihydroxylation of stilbene. NMR experiments showed that these ligands were too bulky to coordinate to osmium. Less hindered analogues of these ligands were prepared and some were shown to act as ligands in dihydroxylation reactions but with poor enantioselectivity (e.e. 10%). The diamines have also been briefly evaluated as ligands in rhodium-catalyzed hydroformylation and copper-catalyzed phenolic coupling reactions. Once again, only low enantioselectivity was obtained.
