Check Digit Verification of cas no

The CAS Registry Mumber 459454-27-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,9,4,5 and 4 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 459454-27:
(8*4)+(7*5)+(6*9)+(5*4)+(4*5)+(3*4)+(2*2)+(1*7)=184
184 % 10 = 4
So 459454-27-4 is a valid CAS Registry Number.

First attempts at differential diastereoselection in catalytic reactions of N-chirally substituted dirhodium(II) tetrakis[methyl 2-oxoimidazolidine-4(S)-carboxylates] with diazoacetates

Doyle,Timmons,Arndt,Duursma,Colyer,Bruenner

, p. 2156 - 2161 (2007/10/03)

Chiral attachments on 2-oxoimidazolidine-4(S)-carboxylate ligands for dirhodium(II) can provide differential diastereoselection in catalytic reactions of diazo compounds. The synthesis of these heterocyclic ligands from the readily available amino acid as
