Z-1,2-dicyano-1,2-bisethene is a complex organic compound with the molecular formula C20H20N2S2. It is characterized by a conjugated diene structure with two cyano groups (-CN) attached to the terminal carbons, and two o-(2-methylthioethyl)phenyl groups attached to the central carbons. The compound exhibits a trans (Z) configuration, which refers to the arrangement of the substituents around the double bond, with the larger groups being on opposite sides of the bond. This specific arrangement influences the compound's physical and chemical properties, such as its reactivity and stability. The presence of sulfur atoms in the molecule also contributes to its unique chemical behavior, making it a potentially interesting candidate for various applications in organic chemistry and materials science.

Check Digit Verification of cas no

The CAS Registry Mumber 87672-57-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,7 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87672-57:
(7*8)+(6*7)+(5*6)+(4*7)+(3*2)+(2*5)+(1*7)=179
179 % 10 = 9
So 87672-57-9 is a valid CAS Registry Number.
