Check Digit Verification of cas no
The CAS Registry Mumber 256221-90-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,2,2 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 256221-90:
(8*2)+(7*5)+(6*6)+(5*2)+(4*2)+(3*1)+(2*9)+(1*0)=126
126 % 10 = 6
So 256221-90-6 is a valid CAS Registry Number.

Stereoselective hydrogenation and ozonolysis of iridoids. Conversion into carbocyclic nucleoside analogues
Franzyk, Henrik,Stermitz, Frank R.
, p. 1646 - 1654 (2007/10/03)
Stereoselective hydrogenation of the iridoids geniposide (9) and aucubin (19) was achieved by using the 1-methyl-1- methoxyethyl ether as a protecting group for the allylic alcohol, as it enhanced the stereoselectivity and prevented undesired hydrogenolysis. Ozonolysis of the hydrogenation product from 9, adoxoside (11), with reductive workup, afforded either a chiral lactone (25) or a chiral polyol (26), depending on the reduction conditions. Polyol 26 was subjected to protecting-group manipulation and subsequent oxidation and reductions to yield cyclopentane building blocks (29-34), which, by Mitsunobu couplings with purines, afforded carbocyclic nucleoside analogues (7, 8, and 35).
