109977-98-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109977-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,7 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109977-98:
(8*1)+(7*0)+(6*9)+(5*9)+(4*7)+(3*7)+(2*9)+(1*8)=182
182 % 10 = 2
So 109977-98-2 is a valid CAS Registry Number.

Synthesis of 2-Desoxy-α-O-glycopeptides by the N-Iodosuccinimide (NIS) Procedure
Kottenhahn, Matthias,Kessler, Horst
, p. 727 - 744 (2007/10/02)
Glycosidation of amino acid/peptide derivatives of serine, threonine, or hydroxyproline with glycals like tris-O-acetyl-D-glucal 1 or tris-O-acetyl-D-galactal 2 and N-iodosuccinimide (NIS) gives 2-deoxy-2-iodo-α-O-glycopeptides with high yields and excell
