6584-69-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6584-69-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,8 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6584-69:
(6*6)+(5*5)+(4*8)+(3*4)+(2*6)+(1*9)=126
126 % 10 = 6
So 6584-69-6 is a valid CAS Registry Number.

Triterpene Glycosides and Aglycones of Sea Cucumbers Holothuria atra and H. scabra (Holothurideae)

Sarma, Nittala S.,Anjaneyulu, A. S. R.,Rao, C. B. S.,Venkateswarlu, Y.

, p. 715 - 721 (2007/10/02)

From the acid hydrolysates of the methanol extracts of the sea cucumbers Holothuria atra and H. scabra (phylum: echinodermata; fam: Holothurideae) collected at Mandapam coast (Tamil Nadu), a total of nine Holothuria sapogenins (compounds A-G, L and M) and two glycosides (H and K) have been isolated by column chromatography and characterised by spectral (UV, IR, PMR and mass) data.Compound C is established as the novel 11-keto-9(11)-dihydro-22,25-oxidoholothurinogenin (III).Compound D (isolated as acetate) is the new 3β-acetoxy-12β-methoxy-7,8-dihydroholothurinogenin (IVa).Compounds F and G (isolated as acetates) are identified as 3β,12α-diacetoxy-7,8-dihydroholothurinogenin (VIa) and 3β,12α-diacetoxy-7,8-dihydro-22,25-oxidoholothurinogenin (VIIa) respectively.For the first time, these two genuine aglycones have been isolated as survivors of acid hydrolysis.Glycoside H is identified as the unique 3-O-(β-D-xylopyranosyl)-22,25-oxidoholothurinogenin (VIII).The remaining six compounds (A, B, E, L, M and glycoside K) are all known compounds; however these are reported for the first time from H. atra and H. scabra (except compound A in both and compound B in H. atra).
