204992-90-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 204992-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,9,9 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 204992-90:
(8*2)+(7*0)+(6*4)+(5*9)+(4*9)+(3*2)+(2*9)+(1*0)=145
145 % 10 = 5
So 204992-90-5 is a valid CAS Registry Number.

Convergent synthesis of N-linked glycopeptides on a solid support
Roberge,Beebe,Danishefsky
, p. 3915 - 3927 (2007/10/03)
Solid-supported synthesis can be conducted to produce a variety of glycopeptides in good overall yields. The carbohydrates are formed by the glycal assembly method. The polymer-bound construct terminates in a glycal. The terminal double bond can be functi
