98870-70-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98870-70-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,8,7 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 98870-70:
(7*9)+(6*8)+(5*8)+(4*7)+(3*0)+(2*7)+(1*0)=193
193 % 10 = 3
So 98870-70-3 is a valid CAS Registry Number.

Synthesis of methyl α- and β-aminofluorodeoxypyranosides
Picq,Anker,Rousset,Laurent
, p. 5619 - 5622 (1983)
Methyl α,β aminofluorodeoxypyranosides are synthesized in three steps from N,N-diallylaminosugars: O-methanesulfonylation followed with treatment by Et3N,3HF leads to a fluorinated compound; N,N-dideallylation gives the expected product.
