The chemical compound "2'-<2,4-Difluor-phenyl>-11β,17,21-trihydroxy-6,16α-dimethyl-20-oxo-pregna-4,6-dieno[3,2-c]pyrazol" is a complex steroidal molecule with a unique structure. It features a pregnane core, which is a type of steroid with a specific carbon skeleton. The molecule is characterized by the presence of a pyrazole ring fused to the pregnane structure, indicating a heterocyclic compound. The 2,4-difluoro-phenyl group attached to the 2' position introduces two fluorine atoms into the phenyl ring, which can significantly influence the compound's reactivity and physical properties. The trihydroxy groups at the 11β, 17, and 21 positions, along with the dimethyl groups at the 6 and 16α positions, contribute to the molecule's hydrophilic and steric properties. The 20-oxo group indicates the presence of a carbonyl functional group, which can participate in various chemical reactions. 2'-<2.4-Difluor-phenyl>-11β.17.21-trihydroxy-6.16α-dimethyl-20-oxo-pregna-4.6-dieno<3.2-c>pyrazol represents a specialized area of organic chemistry, potentially with applications in pharmaceuticals or as a research tool in the study of steroidal compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 1958-82-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,5 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1958-82:
(6*1)+(5*9)+(4*5)+(3*8)+(2*8)+(1*2)=113
113 % 10 = 3
So 1958-82-3 is a valid CAS Registry Number.
