Check Digit Verification of cas no

The CAS Registry Mumber 128302-65-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,3,0 and 2 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128302-65:
(8*1)+(7*2)+(6*8)+(5*3)+(4*0)+(3*2)+(2*6)+(1*5)=108
108 % 10 = 8
So 128302-65-8 is a valid CAS Registry Number.

Synthesis and Conformational Analysis of Epindolidione-Derived Peptide Models for β-Sheet Formation

Kemp, D. S.,Bowen, Benjamin R.,Muendel, Christopher C.

, p. 4650 - 4657 (1990)

Synthesis of 2,8-diaminoepindolidione (2,8-diaminodibenzonaphthyridine-6,12(5,11H)-dione) in 19percent yield from p-nitroaniline is reported, as well as further conversion to 2,8-bis(Boc-L-Pro-Xxx)epindolidione (Xxx=Gly, D-Ala) and then to 2,8-bis(OC(Yyy-Zzz-NMe2)-L-Pro-Xxx)epindolidione (Yyy=Gly, L-Ala, D-Ala; Zzz=Gly, L-Phe, D-Phe).The β-turn-forming tendencies of the series 2,8-bis(X-L-Pro-D-Ala)epindolidione, where X=Ac, Boc, and COGlyOEt, are assigned from 1H NMR evidence.
