Check Digit Verification of cas no

The CAS Registry Mumber 221020-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,0,2 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 221020-89:
(8*2)+(7*2)+(6*1)+(5*0)+(4*2)+(3*0)+(2*8)+(1*9)=69
69 % 10 = 9
So 221020-89-9 is a valid CAS Registry Number.

Novel synthesis of L-iduronic acid using trehalose as the disaccharidic starting material

Hinou, Hiroshi,Kurosawa, Hidehiro,Matsuoka, Koji,Terunuma, Daiyo,Kuzuhara, Hiroyoshi

, p. 1501 - 1504 (2007/10/03)

For the preparation of L-iduronic acid, trehalose was converted into a derivative of a novel disaccharide, β-L-idopyranosyl β-L-idopyranoside, through diastereoselective hydroboration of the 5,5'-di-eno intermediate. The 6- and 6'-hydroxy groups were then oxidized in two steps to give a disaccharide composed of 2 units of L-iduronate moieties, which underwent acidic cleavage of the glycosidic bond to give the target compound.
