2,3'-Dichlor-azobenzol, also known as 2,3'-dichloroazobenzene, is an organic compound characterized by the presence of two chlorine atoms and an azo group (-N=N-) within its molecular structure. This aromatic compound is formed by the substitution of two hydrogen atoms in the benzene ring with chlorine atoms at the 2nd and 3rd positions, and the azo group is attached between the two benzene rings. It is a yellow crystalline solid with potential applications in the synthesis of dyes and pigments. Due to its chemical structure, 2,3'-dichloroazobenzene may exhibit certain toxicological properties, and appropriate safety measures should be taken when handling 2.3'-Dichlor-azobenzol.

The CAS Registry Mumber 2528-64-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,2 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2528-64:
(6*2)+(5*5)+(4*2)+(3*8)+(2*6)+(1*4)=85
85 % 10 = 5
So 2528-64-5 is a valid CAS Registry Number.
