139190-77-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139190-77-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,9 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139190-77:
(8*1)+(7*3)+(6*9)+(5*1)+(4*9)+(3*0)+(2*7)+(1*7)=145
145 % 10 = 5
So 139190-77-5 is a valid CAS Registry Number.

Highly stereoselective glycosylation by conformational assistance of glycosyl donor
Toshima, Kazunobu,Nozaki, Yuko,Tatsuta, Kuniaki
, p. 6887 - 6890 (2007/10/02)
Highly α-stereoselective glycosylation of 2-deoxy-D-fucose was achieved by use of the conformational assistance of the rigid glycosyl donor 2. The selectivity of the glycosylation of 2 was much higher than that of 3 which had a normal chair conformation.
