Purification Methods
Sennoside A (bianthraquinonyl-bis-glucoside R,R-enantiomer) [81-27-6] M 862.7, m 220 -2 4 0o(dec), [ ] D -164o (c 0.1, Me2CO/H2O 6:4), [ ] D -24o (c 0.2, 70% aqueous dioxane). Sennoside A forms yellow crystals from aqueous acetone, 2-ethoxyethanol or large volumes of H2O. [Stoll et al. Helv Chim Acta 32 1896 1900, Beilstein 17 III/IV 3403.]
Check Digit Verification of cas no
The CAS Registry Mumber 81-27-6 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81-27:
(4*8)+(3*1)+(2*2)+(1*7)=46
46 % 10 = 6
So 81-27-6 is a valid CAS Registry Number.
