82255-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82255-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,5 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 82255-40:
(7*8)+(6*2)+(5*2)+(4*5)+(3*5)+(2*4)+(1*0)=121
121 % 10 = 1
So 82255-40-1 is a valid CAS Registry Number.

Ouverture d'epoxydes par les hydroxyurees; synthese de β-ureidoxyalcools
Meslouhi, Hamza El,Petrus, Clement
, p. 37 - 42 (2007/10/02)
The base-catalysed opening of epoxides by hydroxyurea and its N3-phenyl derivative is described.This provides a method of synthesis of new derivatives: β-ureidoxyalcohols and ureidoxydiols.The observed results confirm the selective nucleophilic
