6434-57-7 Usage

Uses

Used in Industrial Applications:
Sudan I is used as a coloring agent in the industrial sector for oils, waxes, and polishes due to its bright red-orange color and solubility in organic solvents.
Used in Regulatory Purposes:
Despite its restrictions and ban in food and cosmetic products, Sudan I is still used in some industries. As a result, it is subject to strict regulation to ensure minimal human exposure and to monitor its presence in products.

Check Digit Verification of cas no

The CAS Registry Mumber 6434-57-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,3 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6434-57:
(6*6)+(5*4)+(4*3)+(3*4)+(2*5)+(1*7)=97
97 % 10 = 7
So 6434-57-7 is a valid CAS Registry Number.
