Originator

ICI 15688,ICI

Manufacturing Process

33 parts of diethyl sulphate are added to 20 parts of diethiolisophthalic acid (MP 245°-247°C prepared by the reaction of isophthalylchloride with sodium hydrogen sulphide) in 125 parts of 8% aqueous sodium hydroxide solution at 20°C and the mixture is then heated at 40°-50°C during one hour. The mixture is then cooled and extracted with 250 parts of benzene, in three portions. The benzene extract is washed with water and dried and the benzene is distilled. The residue is then distilled under reduced pressure to give diethyl dithioisophthalate, BP 210°-215°C/15 mm.

Therapeutic Function

Leprostatic

Check Digit Verification of cas no

The CAS Registry Mumber 584-69-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,8 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 584-69:
(5*5)+(4*8)+(3*4)+(2*6)+(1*9)=90
90 % 10 = 0
So 584-69-0 is a valid CAS Registry Number.
