537718-22-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 537718-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,7,7,1 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 537718-22:
(8*5)+(7*3)+(6*7)+(5*7)+(4*1)+(3*8)+(2*2)+(1*2)=172
172 % 10 = 2
So 537718-22-2 is a valid CAS Registry Number.

Indium-catalyzed reaction for the synthesis of carbamates and carbonates: selective protection of amino groups

Kim, Joong-Gon,Jang, Doo Ok

experimental part, p. 2688 - 2692 (2009/08/09)

We developed a simple, efficient, and selective method for preparing organic carbamates and carbonates using a catalytic amount of indium. A wide range of carbamates and carbonates were synthesized in high yields. The method is also applicable to the selective protection of amino groups under mild conditions.

New process for the preparation of methyl carbonates

Wuts, Peter G. M.,Ashford, Scott W.,Anderson, Andrew M.,Atkins, Joseph R.

, p. 1483 - 1485 (2007/10/03)

(Matrix presented) The methyl carbonate of HOBt was developed for the conversion of alcohols to carbonates. This method is superior to the use of methyl chloroformate or methyl pyrocarbonate, especially with more hindered alcohols. The reagent is a stable solid that is easily prepared on a multigram scale.
