Check Digit Verification of cas no

The CAS Registry Mumber 79118-19-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,1,1 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 79118-19:
(7*7)+(6*9)+(5*1)+(4*1)+(3*8)+(2*1)+(1*9)=147
147 % 10 = 7
So 79118-19-7 is a valid CAS Registry Number.

Synthesis of the Major Component of Alamethicin

Gisin, B.F.,Davis, D.G.,Borowska, Z.K.,Hall, J.E.,Kobayashi, S.

, p. 6373 - 6377 (2007/10/02)

Alamethicin (ALA), a natural membrane-active antibiotic, consists of several components.The major component, ALA I, was isolated in pure form and compared with the synthetic peptide acetyl-Aib-Pro-Aib-Ala-Aib-Ala-Gln-Aib-Val-Aib-Gly-Leu-Aib-Pro-Val-Aib-Aib-Glu-Gln-Phol obtained by stepwise segment condensation on a polystyrene support.The synthetic and natural products appeared essentially identical by amino acid analysis, high performance liquid chromatography, 600-MHz proton nuclear magnetic resonance spectroscopy, mass spectrometry, electrical activity in lipid bilayer membranes, and antimicrobial activity.It is concluded that ALA I has the structure indicated above.
