Check Digit Verification of cas no

The CAS Registry Mumber 97241-10-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,2,4 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 97241-10:
(7*9)+(6*7)+(5*2)+(4*4)+(3*1)+(2*1)+(1*0)=136
136 % 10 = 6
So 97241-10-6 is a valid CAS Registry Number.

CHIRAL INDUCTION IN BILIVERDIN COVALENTLY BOUND TO AMINO ACIDS

Haidl, Ewald,Krois, Daniel,Lehner, Harald

, p. 421 - 426 (2007/10/02)

Amidation of the carboxy groups of biliverdin-IXα (2) with the appropiate (S)-amino acid methyl ester yields the optically active derivatives (3)-(8) which exhibit exceedingly strong Cotton effects in their visible and near-u.v. absorption bands.This is due to theinfluence of the chiral centre on the population of helical conformers of the bilatriene moity across five bond lengths.The magnitude of the c.d. observed depends on the steric requirements of the amino acid and the polarity of the solvent.The chiral induction is interpreted in terms of intramolecular interactions of both side chains exerted from different sides of the bilatriene helix by hydrogen bonds.Both the donor and the acceptor sites of the amino acid residues are involved in the chiral association with the bilatriene backbone.
