858129-89-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 858129-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,8,1,2 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 858129-89:
(8*8)+(7*5)+(6*8)+(5*1)+(4*2)+(3*9)+(2*8)+(1*9)=212
212 % 10 = 2
So 858129-89-2 is a valid CAS Registry Number.

Synthesis of a (1→3)-linked α-L-fucose tetrasaccharide
Ludewig, Michael,Thiem, Joachim
, p. 1768 - 1780 (2007/10/03)
Orthoester-protected benzyl and methyl 1-thiofucopyranosides could be opened to give fucopyranosides unblocked at position 3. Convergent glycosylations of such donors and acceptors led to the corresponding disaccharides, and their block condensation could
