5520-77-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5520-77-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,2 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5520-77:
(6*5)+(5*5)+(4*2)+(3*0)+(2*7)+(1*7)=84
84 % 10 = 4
So 5520-77-4 is a valid CAS Registry Number.
