Check Digit Verification of cas no

The CAS Registry Mumber 130834-77-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,8,3 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130834-77:
(8*1)+(7*3)+(6*0)+(5*8)+(4*3)+(3*4)+(2*7)+(1*7)=114
114 % 10 = 4
So 130834-77-4 is a valid CAS Registry Number.

31P NMR NON-EQUIVALENCE OF THE DIASTEREOISOMERIC PHOSPHONODIDEPSIPEPTIDES. PART II

Glowacki, Zdzislaw,Hoffmann, Maria

, p. 171 - 176 (2007/10/02)

31P chemical shifts are reported for 24 different models of diastereomeric phosphonodidepsipeptides coupled from the N-protected L-aminoacids and dibenzyl esters of chiral 1-hydroxyalkylphosphonic acids.The 31 P NMR nonequivalence variations with the changing of didepsipeptide structure, solvent and temperature were investigated.Amide cis-trans isomerism were observed in the case of Z-L-proline derived didepsipeptides.Key words: Enantiomeric excess; 1-hydroxyalkylphosphonic acids; 31P magnetic nonequivalence; phosphonodidepsipeptides.
