Check Digit Verification of cas no
The CAS Registry Mumber 556068-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,6,0,6 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 556068-53:
(8*5)+(7*5)+(6*6)+(5*0)+(4*6)+(3*8)+(2*5)+(1*3)=172
172 % 10 = 2
So 556068-53-2 is a valid CAS Registry Number.

Determination of the absolute stereochemistry of Etzionin
Vaz, Esther,Fernandez-Suarez, Miryam,Munoz, Luis
, p. 1935 - 1942 (2007/10/03)
The absolute configuration of Etzionin, a marine peptide-like compound isolated in 1989 from a red tunicate collected from the Red Sea has been determined by a combination of synthetic and spectroscopic procedures. Finally, its absolute stereochemistry ha
