Check Digit Verification of cas no

The CAS Registry Mumber 454695-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,4,6,9 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 454695-23:
(8*4)+(7*5)+(6*4)+(5*6)+(4*9)+(3*5)+(2*2)+(1*3)=179
179 % 10 = 9
So 454695-23-9 is a valid CAS Registry Number.

Combinatorial development of chiral phosphoramidite-ligands for enantioselective conjugate addition reactions.

Huttenloch, Oliver,Laxman, Eltepu,Waldmann, Herbert

, p. 673 - 675 (2002)

Chiral phosphoramidite ligands embodying bispidine frame work and a binaphthyl phosphoramidite for Cu-catalysed enantioselective conjugate addition reactions were developed employing principles of combinatorial and solid phase chemistry.
