812697-71-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 812697-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,2,6,9 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 812697-71:
(8*8)+(7*1)+(6*2)+(5*6)+(4*9)+(3*7)+(2*7)+(1*1)=185
185 % 10 = 5
So 812697-71-5 is a valid CAS Registry Number.

Stereoselective N-glycosylation by Staudinger ligation
He, Yi,Hinklin, Ronald J.,Chang, Jiyoung,Kiessling, Laura L.
, p. 4479 - 4482 (2007/10/03)
(Chemical equation presented) Stereoselective methods for the chemical synthesis of β-N-glycosyl amides are needed to generate glycopeptides and glycoproteins. Here, we report that the Staudinger ligation can be used to form glycosylated asparagine deriva
