Description
Acid Yellow 117 is a yellow-brown powder that is soluble in water. It exhibits a yellow color in its aqueous solution, and when hydrochloric acid or sodium hydroxide is added, the color becomes tender yellow. It has good levelness and discharge properties, but its fastness to hair color on silk is relatively poor.

Check Digit Verification of cas no
The CAS Registry Mumber 6459-70-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,5 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6459-70:
(6*6)+(5*4)+(4*5)+(3*9)+(2*7)+(1*0)=117
117 % 10 = 7
So 6459-70-7 is a valid CAS Registry Number.
