113531-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113531-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,5,3 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 113531-33:
(8*1)+(7*1)+(6*3)+(5*5)+(4*3)+(3*1)+(2*3)+(1*3)=82
82 % 10 = 2
So 113531-33-2 is a valid CAS Registry Number.

Use of Diethylaminosulfur Trifluoride in an Efficient Synthesis of (S)-N--5-(3-Fluoropropyl)-2-Methoxybenzamide
Mukherjee, Jogeshwar
, p. 151 - 154 (1990)
Diethylaminosulfur trifluoride (DAST) was used to prepare 2,6-dimethoxybenzoyl fluoride, which on reaction with (S)-N-ethyl-2-aminomethylpyrrolidine gave (S)-N--2,6-dimethoxybenzamide in > 95percent yields.A three-step effi
