Benzencnessulfonic acid, 2,2'-(1,2-ethenediyl)bis[5-[4,6-bis[(2-sulfoethyl)amino]-1,3,5-triazin-2-yl]amino]-, hexasodium salt is a complex organic compound with the chemical formula C24H24N12Na6O12S4. It is a derivative of benzenesulfonic acid, featuring a benzene ring with two ethylene bridges connecting two 1,3,5-triazine moieties. Each triazine ring is substituted with two (2-sulfoethyl)amino groups at the 4 and 6 positions, and an amino group at the 2 position. The compound is a hexasodium salt, indicating that it contains six sodium ions to balance the negative charges from the sulfonic acid groups. This chemical is known for its use as a dispersing agent in various applications, particularly in the dyeing and printing of textiles, due to its ability to disperse dyes evenly and improve their solubility in water.

The CAS Registry Mumber 3656-31-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,5 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3656-31:
(6*3)+(5*6)+(4*5)+(3*6)+(2*3)+(1*1)=93
93 % 10 = 3
So 3656-31-3 is a valid CAS Registry Number.
