Check Digit Verification of cas no

The CAS Registry Mumber 286420-55-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,6,4,2 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 286420-55:
(8*2)+(7*8)+(6*6)+(5*4)+(4*2)+(3*0)+(2*5)+(1*5)=151
151 % 10 = 1
So 286420-55-1 is a valid CAS Registry Number.

A concise synthesis of the 6-O- and 6'-O-sulfated analogues of the sialyl Lewis X tetrasaccharide

Misra, Anup Kumar,Ding, Yili,Lowe, John B.,Hindsgaul, Ole

, p. 1505 - 1509 (2007/10/03)

The octyl glycoside of the sialyl Lewis X tetrasaccharide and its 6-O-sulfated and 6'-O-sulfated analogues were chemically synthesized in a concise manner starting from readily accessible monosaccharide intermediates. The synthesis involved formation of an orthogonally protected tetrasaccharide intermediate from which all three materials were prepared. A selective catalytic hydrogenolysis of four O-benzyl ethers in presence of a 4,6-O-benzylidene group was the key step in the synthetic scheme. (C) 2000 Elsevier Science Ltd. All rights reserved.
