204918-52-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 204918-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,9,1 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 204918-52:
(8*2)+(7*0)+(6*4)+(5*9)+(4*1)+(3*8)+(2*5)+(1*2)=125
125 % 10 = 5
So 204918-52-5 is a valid CAS Registry Number.

Preparation of the tri-arabino di-mycolate fragment of mycobacterial arabinogalactan from defined synthetic mycolic acids

Mohammed, Mohsin O.,Al Dulayymi, Juma'a R.,Baird, Mark S.

, p. 36 - 42 (2017)

An efficient synthetic approach to tri-arabino di-mycolates, using structurally defined synthetic α-, keto and methoxy mycolic acids is described.

Synthetic arabinofuranosyl oligosaccharides as mycobacterial arabinosyltransferase substrates

Ayers, Joseph D.,Lowary, Todd L.,Morehouse, Caroline B.,Besra, Gurdyal S.

, p. 437 - 442 (2007/10/03)

A series of arabinofuranosyl oligosaccharides found as constituent parts of the polysaccharide portion of the cell wall of Mycobacterium tuberculosis have been chemically synthesized. Screening of these oligosaccharidss as substrates for arabinosyltransferases present in mycobacterial membrane preparations suggests that modified oligosaccharide analogs as small as disaccharides may be inhibitors of glycan biosynthesis. Such inhibitors would be of potential utility as lead compounds in the identification of new drugs for the treatment of mycobacterial infections.
