Check Digit Verification of cas no

The CAS Registry Mumber 163887-30-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,8,8 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 163887-30:
(8*1)+(7*6)+(6*3)+(5*8)+(4*8)+(3*7)+(2*3)+(1*0)=167
167 % 10 = 7
So 163887-30-7 is a valid CAS Registry Number.

Determination of the complete absolute configuration of petriellin A

Aurelio, Luigi,Brownlee, Robert T. C.,Dang, Jason,Hughes, Andrew B.,Polya, Gideon M.

, p. 407 - 414 (2008/02/04)

We report the full structural determination of the depsipeptide petriellin A. The absolute configuration of the amino acid residues, N-methyl isoleucine and N-methyl threonine, have been determined by a combination of HPLC and TLC comparison of synthetic Marfey's derivatives and Marfey's derivatives of the natural product hydrolysate. The configuration of the chiral centres in these two N-methylated residues was found to be the same as those of the common unmethylated l-amino acids. CSIRO 2006.
