91614-68-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91614-68-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,1 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91614-68:
(7*9)+(6*1)+(5*6)+(4*1)+(3*4)+(2*6)+(1*8)=135
135 % 10 = 5
So 91614-68-5 is a valid CAS Registry Number.

As a part of our search for new potent analgesic agents, novel fused pyrazole derivatives were synthesized.The reaction of 3-substituted-5-hydroxypyrazole (I) with ethyl 2-substituted (for example COCH3 or CO2C2H5) acylacetates (II) gave mainly pyrazolo1
