Check Digit Verification of cas no

The CAS Registry Mumber 47285-65-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,7,2,8 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 47285-65:
(7*4)+(6*7)+(5*2)+(4*8)+(3*5)+(2*6)+(1*5)=144
144 % 10 = 4
So 47285-65-4 is a valid CAS Registry Number.

Conformational analysis of β-turn structure in tetrapeptides containing proline or proline analogs

Hayashi, Takashi,Asai, Tomohito,Ogoshi, Hisanobu

, p. 3039 - 3042 (1997)

In order to evaluate the influence of cyclic secondary amino acids on the stability of β-turn structure, we have prepared Ac-Gly-L-Xxx-L-Leu-Gly-N(CH3)2 (Xxx = Aze, 4-membered ring: 1, Xxx = Pro, 5-membered ring: 2, Xxx = Pip, 6-membered ring: 3). The NOE cross peaks that support β-turn structure were observed in 1-3. The NOE cross peak between both terminals of the synthetic peptides, however, was observed only in the NOESY spectra of 2. This result indicates that 5-membered ring side chain in proline plays a very important role in the formation of β-hairpin structure.
