135763-39-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135763-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,7,6 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 135763-39:
(8*1)+(7*3)+(6*5)+(5*7)+(4*6)+(3*3)+(2*3)+(1*9)=142
142 % 10 = 2
So 135763-39-2 is a valid CAS Registry Number.

Enzymatic deprotection of methylthiomethyl esters: Synthesis of O-(carbamoyl) and O-(sulfamoyl)salicylic acids
Kamal
, p. 1293 - 1299 (2007/10/02)
An enzymatic selective deprotection of methylthiomethyl esters via their sulfone derivatives in presence of labile carbamoyloxy as well as sulfamoyloxy functionalities lead to the formation of O-(carbamoyl) and O-(sulfamoyl)salicylic acids respectively.
