Definition
ChEBI: An organosulfonic acid comprising stilbene having 4-anilino-6-[bis(2-hydroxyethyl)amino]-1,3,5-triazin-2-yl}amino groups at the 4 and 4'-positions and sulfo groups at the 2- and 2'-positions.
Check Digit Verification of cas no
The CAS Registry Mumber 4404-43-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,0 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4404-43:
(6*4)+(5*4)+(4*0)+(3*4)+(2*4)+(1*3)=67
67 % 10 = 7
So 4404-43-7 is a valid CAS Registry Number.
