75921-90-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75921-90-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,2 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75921-90:
(7*7)+(6*5)+(5*9)+(4*2)+(3*1)+(2*9)+(1*0)=153
153 % 10 = 3
So 75921-90-3 is a valid CAS Registry Number.

Forbeside E: a novel sulfated sterol glycoside from Asterias forbesi

Findlay, John A.,He, Zheng-Quan,Jaseja, Mahesh

, p. 2078 - 2080 (2007/10/02)

The structure of forbeside E, a minor constituent of the saponin fraction of the starfish Asterias forbesi, has been identified as the disodium salt of (20R)-5α-pregn-9(11)ene-3β-sulfo-oxy-6α--20-ol, principally by 2D-COSY, DQ COSY, HCORR, and DEPT experiments.Sodium thornasterol-3-O-sulfate has been isolated as a natural product from the same organism.Key words: sulfated sterol glycoside, Asterias forbesi metabolites, sodium thornasterol-3-O-sulfate, asterogenol rearrangement.

Marine organic chemistry. IV. Isolation of (20R)-5-α-pregn-9(11)-ene-3β,6α,20-triol from the saponins of the starfish, Asterias forbesi and Asterias vulgaris, and its synthesis

Apsimon, John W.,Badripersaud, Satyanand,Buccini, John A.,Eenkhoorn, Joop

, p. 2703 - 2708 (2007/10/02)

A minor constituent of the saponin hydrolysate of the starfishes Asterias forbesi and Asterias vulgaris is shown to be (20R)-5α-pregn-9(11)-ene-3β,6α,20-triol by synthesis from 11-oxoprogesterone.The occurrence of the reduced progesterone side chain could have imlications concerning the origins of progesterone-type compounds in saponin hydrolysates from starfish.
