206050-51-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 206050-51-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,0,5 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 206050-51:
(8*2)+(7*0)+(6*6)+(5*0)+(4*5)+(3*0)+(2*5)+(1*1)=83
83 % 10 = 3
So 206050-51-3 is a valid CAS Registry Number.

Synthesis of thieno[3,2-d][1,2,3]thiadiazoles. New mechanistic aspects of the hurd-mori reaction
Stanetty, Peter,Kremslehner, Manfred
, p. 259 - 266 (2007/10/03)
The synthesis of new thieno[3,2-d][1,2,3]thiadiazole derivatives is described. A modified reaction mechanism of the Hurd-Mori reaction is presented showing better agreement with the obtained results.
