Check Digit Verification of cas no

The CAS Registry Mumber 52121-55-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,1,2 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 52121-55:
(7*5)+(6*2)+(5*1)+(4*2)+(3*1)+(2*5)+(1*5)=78
78 % 10 = 8
