337919-52-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 337919-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,7,9,1 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 337919-52:
(8*3)+(7*3)+(6*7)+(5*9)+(4*1)+(3*9)+(2*5)+(1*2)=175
175 % 10 = 5
So 337919-52-5 is a valid CAS Registry Number.

Synthesis of 2-(4-tolyloxyacetylamido)-5-aryloxymethyl-1,3,4-thiadiazoles under microwave irradiation
Wang,Li,Da
, p. 19 - 26 (2001)
2-(4-Tolyloxyacetylamido)-5-aryloxymethyl-1,3,4-thiadiazoles (IIa-j) are synthesized under microwave irradiation by the cyclization of 1-aryloxyacetyl-4-(4-tolyloxyacetyl)-thiosemicarbazides (Ia-j) in the presence of glacial acetic acid.
