Check Digit Verification of cas no

The CAS Registry Mumber 135087-18-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,0,8 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 135087-18:
(8*1)+(7*3)+(6*5)+(5*0)+(4*8)+(3*7)+(2*1)+(1*8)=122
122 % 10 = 2
So 135087-18-2 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.
