652971-69-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 652971-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,2,9,7 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 652971-69:
(8*6)+(7*5)+(6*2)+(5*9)+(4*7)+(3*1)+(2*6)+(1*9)=192
192 % 10 = 2
So 652971-69-2 is a valid CAS Registry Number.

Various acetanilides (1) were treated with DMF and POCl3 complex (Vilsmeier's reagent) to obtain 2-chloro-3-quinolinecarboxaldehydes (2). The latter on condensation with thiosemi- carbazide in alcohol gave the corresponding thiosemicarbazones (
