1253513-75-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1253513-75-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,5,1 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1253513-75:
(9*1)+(8*2)+(7*5)+(6*3)+(5*5)+(4*1)+(3*3)+(2*7)+(1*5)=135
135 % 10 = 5
So 1253513-75-5 is a valid CAS Registry Number.

Synthesis of heterocyclic new pyrazolyl compounds
Thore,Gupta, Ashwani Kumar
, p. 373 - 376 (2011/12/16)
Condensation of acetophenone with pyrazole aldehyde gave new series of fluorine and chlorine containing chalcones 3. Several pyrazolyl compounds were obtained using compounds 3. The structures of the compounds 3-7 were confirmed by NMR, IR and mass spectr
