147194-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 147194-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,1,9 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 147194-40:
(8*1)+(7*4)+(6*7)+(5*1)+(4*9)+(3*4)+(2*4)+(1*0)=139
139 % 10 = 9
So 147194-40-9 is a valid CAS Registry Number.

A convenient method is proposed for the synthesis of the new heterocyclic system 3-ethylenediamino-1,2,5-oxadiazole-4-carboxamide and its thio analog by intramolecular alkylation of 3-(β-chloroethylamino)-1,2,5-thia(oxa)diazole-4-carboxamides.
