Check Digit Verification of cas no

The CAS Registry Mumber 889128-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,9,1,2 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 889128-40:
(8*8)+(7*8)+(6*9)+(5*1)+(4*2)+(3*8)+(2*4)+(1*0)=219
219 % 10 = 9
So 889128-40-9 is a valid CAS Registry Number.

Synthesis of the peptaibol framework of the anticancer agent culicinin D: Stereochemical assignment of the AHMOD moiety

Hung, Kuo-Yuan,Harris, Paul W. R.,Brimble, Margaret A.

supporting information, p. 5784 - 5787 (2013/01/15)

The postulated structure of the potent anticancer peptaibol culicinin D has been synthesized using Fmoc-based solid-phase peptide synthesis (SPPS). Comparison of the 1H NMR data for the reported structure of culicinin D with the data obtained for the two synthetic polypeptides epimeric at C-6 in the AHMOD unit established the C-6 stereochemistry of the AHMOD residue in the natural product to be (R).
