54934-31-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54934-31-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,9,3 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 54934-31:
(7*5)+(6*4)+(5*9)+(4*3)+(3*4)+(2*3)+(1*1)=135
135 % 10 = 5
So 54934-31-5 is a valid CAS Registry Number.

A FACILE PREPARATION OF THIOL ESTERS FROM CARBOXYLIC ACIDS AND THIOLS
Kim, Sunggak,Yang, Sungbong
, p. 133 - 134 (2007/10/02)
Thiol esters can be conveniently prepared by the reaction of carboxylic acids with thiols and 1-fluoro-2,4,6-trinitrobenzene in the presence of 4-dimethylaminopyridine.The thiol ester formation is found to be very effective for simple carboxylic acids.
