251085-99-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 251085-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,0,8 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 251085-99:
(8*2)+(7*5)+(6*1)+(5*0)+(4*8)+(3*5)+(2*9)+(1*9)=131
131 % 10 = 1
So 251085-99-1 is a valid CAS Registry Number.

Convergent synthesis of (1→2)- and (1→4)-C-linked imino disaccharides
Zhu, Yao-Hua,Vogel, Pierre
, p. 1873 - 1874 (2007/10/03)
A convergent synthesis of (1→2)- and (1→4)-C-linked imino disaccharides was achieved by applying Nozaki-Kishi coupling of a hydroxyproline-derived carbaldehyde with isolevoglucosenone or levoglucosenone derived enol triflates.
