1259987-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1259987-77-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,9,8 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1259987-77:
(9*1)+(8*2)+(7*5)+(6*9)+(5*9)+(4*8)+(3*7)+(2*7)+(1*7)=233
233 % 10 = 3
So 1259987-77-3 is a valid CAS Registry Number.

Everything's under control: A stabilizing fluorine electrostatic interaction has been exploited to control oxonium ion conformation in 2-fluoropyranose derivatives (see scheme). When matched with the inductive nature of the protecting groups, the glycosyl
