Yellow 4, also known as Sunset Yellow FCF or E110, is a synthetic azo dye commonly used as a food coloring agent to impart a vibrant yellow hue to various products, including beverages, confectionery, and dairy items. It is a water-soluble, orange-yellow powder that is stable under normal conditions and is approved for use in many countries, although its use is restricted or banned in some due to potential health concerns. Yellow 4 is derived from coal tar and is known for its high tinctorial strength, meaning it requires only a small amount to achieve the desired color intensity.

Check Digit Verification of cas no

The CAS Registry Mumber 1342-40-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,4 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1342-40:
(6*1)+(5*3)+(4*4)+(3*2)+(2*4)+(1*0)=51
51 % 10 = 1
So 1342-40-1 is a valid CAS Registry Number.
