on long standing; hygroscopic; fluorescent in
solution under UV radiation. Very
soluble in water, alcohol; insoluble in ether, benzene.
Combustible.
Uses
4-sulphophthalic anhydride can be used in wetting, cleansing, emulsifying, softening, and equalizing agents with textiles. Derivatives have application as surface-active agents.
Check Digit Verification of cas no
The CAS Registry Mumber 134-08-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134-08:
(5*1)+(4*3)+(3*4)+(2*0)+(1*8)=37
37 % 10 = 7
So 134-08-7 is a valid CAS Registry Number.
