Properties and Applications
Yellow light red to red. Deep red powder, odourless. Soluble in water, 0.1% water solution is what with red, can dissolve in glycerin and propylene glycol, slightly soluble in ethanol, insoluble in grease. Has the characteristics of acid dyes. In 100ml 0.2 mol/ L ammonium acetate solution contains 0.001g samples, the maximum absorption wavelength for 499 + 2 nm. Resistance to light sex, heat resistance, the salt resistance, resistance to acidic sex is strong. To such as citric acid, tartaric acid stability. Good alkali resistance and oxidizing is good, the sulfur dioxide well tolerated.
Check Digit Verification of cas no
The CAS Registry Mumber 25956-17-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,9,5 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 25956-17:
(7*2)+(6*5)+(5*9)+(4*5)+(3*6)+(2*1)+(1*7)=136
136 % 10 = 6
So 25956-17-6 is a valid CAS Registry Number.
