5280-78-4 Usage
Flammability and Explosibility
NotclassifiedCheck Digit Verification of cas no
The CAS Registry Mumber 5280-78-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,8 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.Calculate Digit Verification of CAS Registry Number 5280-78:
(6*5)+(5*2)+(4*8)+(3*0)+(2*7)+(1*8)=94
94 % 10 = 4
So 5280-78-4 is a valid CAS Registry Number.
