848854-42-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 848854-42-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,8,8,5 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 848854-42:
(8*8)+(7*4)+(6*8)+(5*8)+(4*5)+(3*4)+(2*4)+(1*2)=222
222 % 10 = 2
So 848854-42-2 is a valid CAS Registry Number.

Preparation of an analogue of orbicuside A, an unusual cardiac glycoside

Dixon, John T.,Van Heerden, Fanie R.,Holzapfel, Cedric W.

, p. 393 - 401 (2007/10/03)

A steroid containing a multi-linked glycoside, analogous to the bufadienolide orbicuside A, has been prepared. The key steps were (i) the preparation of a 2α-allyloxycarbonyloxy-3β-hydroxy steroid, (ii) a Ferrier reaction between the steroid and a rhamnal derivative, (iii) removal of protecting group and oxidation of the 2-hydroxy group, (iv) dihydroxylation of the pseudoglycal from the sterically more hindered side and finally (v) ring closure by acetal formation under acidic conditions.
