2-[[2-Oxo-1-[(2-methoxy-5-sodiosulfophenyl)aminocarbonyl]propyl]azo]-5-[N'-[3-sodiooxycarbonyl-4-[[2-oxo-1-[(4-sodiosulfophenyl)aminocarbonyl]propyl]azo]phenyl]ureido]benzoic acid sodium salt is a complex organic compound with a unique chemical structure. It is characterized by its yellow to dark yellow color and is soluble in water, producing a golden brown color. 2-[[2-Oxo-1-[(2-methoxy-5-sodiosulfophenyl)aminocarbonyl]propyl]azo]-5-[N'-[3-sodiooxycarbonyl-4-[[2-oxo-1-[(4-sodiosulfophenyl)aminocarbonyl]propyl]azo]phenyl]ureido]benzoic acid sodium salt exhibits resistance to acids and alkalis, as well as good light fastness. It is slightly soluble in alcohol and does not change color when exposed to strong sulfuric acid or when a dye solution is added to a strong hydrochloric acid. However, it does not show any change when a thick sodium hydroxide solution is added.

Check Digit Verification of cas no

The CAS Registry Mumber 6391-32-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,9 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6391-32:
(6*6)+(5*3)+(4*9)+(3*1)+(2*3)+(1*2)=98
98 % 10 = 8
So 6391-32-8 is a valid CAS Registry Number.
