Preparation
C.I. Direct Yellow 11 (C.I. 40000) solution with?Formaldehyde?condensation; Or (E)-2-(2-sulfo-4-nitrostyryl)-5-nitrobenzenesulfonic acid?in the presence of sodium hydroxide solution and Formaldehyde heating.Properties and Applications
yellow to red light yellow. Soluble in water for lemon yellow, not soluble in ethanol and other organic solvents. The strong sulfuric acid for wine, diluted for yellow. The dye solution to join 10% color is more green sulfuric acid; Join rare sodium hydroxide solution reddish change.

1Check Digit Verification of cas no
The CAS Registry Mumber 1325-38-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.Calculate Digit Verification of CAS Registry Number 1325-38:
(6*1)+(5*3)+(4*2)+(3*5)+(2*3)+(1*8)=58
58 % 10 = 8
So 1325-38-8 is a valid CAS Registry Number.
