205391-57-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 205391-57-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,3,9 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 205391-57:
(8*2)+(7*0)+(6*5)+(5*3)+(4*9)+(3*1)+(2*5)+(1*7)=117
117 % 10 = 7
So 205391-57-7 is a valid CAS Registry Number.

Synthesis and properties of ionophore conjugated hypericin derivatives
Altmann, Robert,Falk, Heinz,Gruber, Hermann J.
, p. 235 - 244 (2007/10/03)
Two types of derivatives substituted with ionophoric residues at the ω,ω′-methyl groups of hypericin were synthesized. On the one hand, an open chain triethylene glycol derivative did not form stable complexes with alkali metal ions. Embedded as its deter
