86538-61-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86538-61-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,5,3 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 86538-61:
(7*8)+(6*6)+(5*5)+(4*3)+(3*8)+(2*6)+(1*1)=166
166 % 10 = 6
So 86538-61-6 is a valid CAS Registry Number.

Hetarylpyrazoles. IV. (1) Synthesis and Reactions of 1,5'-Bipyrazoles
Khan, Misbahul Ain,Freitas, Antonio Carlos Carreira
, p. 277 - 279 (2007/10/02)
A number of 1,5'-bipyrazoles were obtained from the condensation of pyrazol-5-ylhydrazine and 1,3-dicarbonyl compounds.Electrophilic substitution reactions of these 1,5'-bipyrazoles occur at the four position of the pyrazole ring.
