Check Digit Verification of cas no

The CAS Registry Mumber 70209-59-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,0 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 70209-59:
(7*7)+(6*0)+(5*2)+(4*0)+(3*9)+(2*5)+(1*9)=105
105 % 10 = 5
So 70209-59-5 is a valid CAS Registry Number.

Bausteine von Oligosacchariden, XX. Synthese der Oligosaccharid-Determinanten der Blutgruppensubstanzen der Type 2 des ABH-Systems. Diskussion der &α-Glycosid-Synthese

Paulsen, Hans,Kolar, Cenek

, p. 306 - 321 (2007/10/02)

The antigenic determinants of type 2 of blood-group substances A and B (23 and 24) as well as blood-group substance H (17) were synthesized by selective glycosidation reactions combined with a series of blocking and deblocking steps.The possibilities and optimization of the α-glycoside synthesis are discussed.In hemagglutination inhibition tests the synthetic haptens A and B of type 2 and type 1 show a similar selective inhibitory effect.In case of hapten H, however, great differences can be observed.Here the type 2 exhibited a strong inhibition activity, whereas type 1 only showed an extremly low activity.This leads to the conclusion that in the determinants of the ABH-system on the surface of erythrocytes the chemical structure of type 2 is predominating.
