92033-49-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92033-49-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,0,3 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 92033-49:
(7*9)+(6*2)+(5*0)+(4*3)+(3*3)+(2*4)+(1*9)=113
113 % 10 = 3
So 92033-49-3 is a valid CAS Registry Number.

A practical synthesis of ureas from phenyl carbamates
Thavonekham, Bounkham
, p. 1189 - 1194 (2007/10/03)
Using DMSO as solvent, a mild and efficient procedure for the synthesis of unsymmetrical N,N'-disubstituted ureas from phenyl carbamates is described. The carbamates are treated with a stoichiometric amount of amine at ambient temperature, generating the
