Acid Blue 142 is a blue powder dye that exhibits green light blue and red light blue colors. It is soluble in strong sulfuric acid, resulting in a yellow-brown colloidal solution that turns lake green upon dilution and forms a precipitate. In nitric acid, it forms an old yellow glue shape. Its aqueous solution is blue lake, and the addition of a small amount of hydrochloric acid or sodium hydroxide slightly changes its color to yellow, with the formation of a precipitate.

2Check Digit Verification of cas no
The CAS Registry Mumber 61723-94-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,7,2 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.Calculate Digit Verification of CAS Registry Number 61723-94:
(7*6)+(6*1)+(5*7)+(4*2)+(3*3)+(2*9)+(1*4)=122
122 % 10 = 2
So 61723-94-2 is a valid CAS Registry Number.
