Check Digit Verification of cas no

The CAS Registry Mumber 1554556-61-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,5,4,5,5 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1554556-61:
(9*1)+(8*5)+(7*5)+(6*4)+(5*5)+(4*5)+(3*6)+(2*6)+(1*1)=184
184 % 10 = 4
So 1554556-61-4 is a valid CAS Registry Number.

Convergent synthesis of a pentasaccharide repeating unit corresponding to the cell wall O-antigen of Salmonella enterica O44

Dhara, Debashis,Mandal, Pintu Kumar,Misra, Anup Kumar

, p. 263 - 267 (2014)

A convergent synthetic strategy has been developed for the synthesis of a pentasaccharide fragment corresponding to the O-antigen of Salmonella enterica O44 strain. An intermediate tetrasaccharide derivative was prepared by a [2+2] block glycosylation of two disaccharide derivatives. The p-methoxybenzyl (PMB) group has been used as the in situ temporary protecting group minimizing the number of functional group manipulation steps. The application of the armed-disarmed glycosylation concept reduced the number of steps in the synthetic strategy. The glycosylation steps were highly stereoselective and high yielding.
