Check Digit Verification of cas no

The CAS Registry Mumber 1632164-60-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,2,1,6 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1632164-60:
(9*1)+(8*6)+(7*3)+(6*2)+(5*1)+(4*6)+(3*4)+(2*6)+(1*0)=143
143 % 10 = 3
So 1632164-60-3 is a valid CAS Registry Number.

Synthesis, structures, and spectroscopic properties of 3-aryl-5-(2-pyridyl) pyrazoles and related pyrazoles

Schowtka, Bjoern,Mueller, Christoph,Goerls, Helmar,Westerhausen, Matthias

supporting information, p. 916 - 925 (2014/04/17)

3-Aryl-5-(2-pyridyl)pyrazoles and related compounds are easily accessible via the reaction of the appropriate 1,3-diketone with hydrazine hydrate. The central pyrazole rings show a far-reaching equalization of the bond lengths. In the crystalline state dimeric and strand-like structures are observed due to the formation of intermolecular N-H...N hydrogen bridges between the pyrazole N-H functionality and a pyrazole or pyridyl base. The structures mainly depend on the steric demand of the aryl groups. Planar 3-aryl-5-(2-pyridyl)pyrazoles also show π stacking reducing the solubility in common organic solvents. Copyright
