121843-92-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 121843-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,8,4 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 121843-92:
(8*1)+(7*2)+(6*1)+(5*8)+(4*4)+(3*3)+(2*9)+(1*2)=113
113 % 10 = 3
So 121843-92-3 is a valid CAS Registry Number.

Chemoselective alcoholysis of acylureas

Kishikawa,Eida,Kohmoto,Yamamoto,Yamada

, p. 173 - 175 (1994)

Two methods for the chemoselective alcoholysis of acylureas were developed to generate esters and amides, respectively. In alcoholysis using sodium methoxide in methanol, methoxide attacked the acyl carbonyl to give the corresponding methyl ester. While in alcoholysis using lithium benzyloxide in diethyl ether, benzyloxide attacked the urea carbonyl to give the amide. The chemoselectivity originates in the different chelating abilities of the metals and the polarity of the solvents.
