Check Digit Verification of cas no

The CAS Registry Mumber 1304696-01-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,4,6,9 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1304696-01:
(9*1)+(8*3)+(7*0)+(6*4)+(5*6)+(4*9)+(3*6)+(2*0)+(1*1)=142
142 % 10 = 2
So 1304696-01-2 is a valid CAS Registry Number.

Convergent synthesis of a common pentasaccharide corresponding to the O-antigen of Escherichia coli O168 and Shigella dysenteriae type 4

Guchhait, Goutam,Misra, Anup Kumar

experimental part, p. 11 - 19 (2012/06/04)

A convenient synthetic strategy of the common acidic pentasaccharide repeating unit corresponding to the O-antigen of enterotoxigenic E. coli O168 and Shigella dysenteriae type 4 has been successfully developed. A stereoselective [2+3] block glycosylation method has been exploited to get the target pentasaccharide derivative. Most of the synthetic intermediates were solid and prepared in high yields from commercially available reducing sugars following a series of protection-deprotection reactions. A α-D-mannose moiety has been used as the source of α-D-glucosamine moiety. A late-stage TEMPO mediated selective oxidation reaction finally resulted in the pentasaccharide containing a glucuronic acid unit.
