1309855-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1309855-99-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,8,5 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1309855-99:
(9*1)+(8*3)+(7*0)+(6*9)+(5*8)+(4*5)+(3*5)+(2*9)+(1*9)=189
189 % 10 = 9
So 1309855-99-9 is a valid CAS Registry Number.

An efficient approach to 2,5-anhydro-glucitol-based 1′-homo-N- nucleoside mimetics
Bhatt, Beenu,Thomson, Robin J.,Von Itzstein, Mark
, p. 2741 - 2743 (2011/06/19)
This Letter describes an efficient synthesis of a range of 1′-homo-N-nucleoside mimetics with a series of 4-substituted 1,2,3-triazoles replacing the natural nucleobase. The synthesis of 6-O-monosulfated 1′-homo-N-nucleoside mimetic derivatives is also discussed.
