143520-19-8 Usage
Uses
2,3,4,6-Tetra-O-benzyl-alpha-D-glucopyranosyl N,N,N’,N’-tetramethylphosphorodiamidate (CAS# 143520-19-8) is a carbohydrate used in the synthesis of oligosaccharides acting as a glycosyl acceptor with its phosphorous moiety acting as a leaving group.
Check Digit Verification of cas no
The CAS Registry Mumber 143520-19-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,5,2 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143520-19:
(8*1)+(7*4)+(6*3)+(5*5)+(4*2)+(3*0)+(2*1)+(1*9)=98
98 % 10 = 8
So 143520-19-8 is a valid CAS Registry Number.

Oligosaccharide synthesis based on glycosyl donors and accepters carrying phosphorus-containing leaving groups

Efficient synthetic strategy for oligosaccharides has been developed by exploiting the difference in anomeric reactivity between glycosyl donors and acceptors carrying phosphorus-containing leaving groups, wherein, the tetramethylphosphoroamidate group plays a pivotal role as anomeric protective group as well as leaving group.
