220689-80-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220689-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,6,8 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 220689-80:
(8*2)+(7*2)+(6*0)+(5*6)+(4*8)+(3*9)+(2*8)+(1*0)=135
135 % 10 = 5
So 220689-80-5 is a valid CAS Registry Number.

An access to glycoconjugate libraries through multicomponent reactions
Lockhoff, Oswald
, p. 3436 - 3439 (2007/10/03)
Four-component reactions: The Ugi reaction of four suitably functionalized carbohydrate derivatives (as a per-O-benzylated amine, an aldehyde, a carboxylic acid, and an isocyanide) allow the effective assembly of diverse compound libraries. The complex gl
