554-77-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 554-77-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 554-77:
(5*5)+(4*5)+(3*4)+(2*7)+(1*7)=78
78 % 10 = 8
So 554-77-8 is a valid CAS Registry Number.
