Check Digit Verification of cas no
The CAS Registry Mumber 34044-34-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,0,4 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 34044-34:
(7*3)+(6*4)+(5*0)+(4*4)+(3*4)+(2*3)+(1*4)=83
83 % 10 = 3
So 34044-34-3 is a valid CAS Registry Number.

Conversion of 2-(trimethylsilyl)ethyl sulfides into thioesters
Grundberg, Hans,Andergran, Magnus,Nilsson, Ulf J.
, p. 1811 - 1814 (2007/10/03)
Treatment of 2-(trimethylsilyl)ethyl sulfides with a carboxylic acid chloride and AgBF4 in CH2Cl2 furnishes the corresponding thioesters in high yields and purities. The conversion of 2-(trimethylsilyl)ethyl sulfides into synthetically versatile thioesters allows such sulfides to be used as sulfhydryl protective groups, since such sulfides are easily prepared and are stable towards many reaction conditions encountered in organic syntheses.
