Check Digit Verification of cas no

The CAS Registry Mumber 477248-71-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,7,2,4 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 477248-71:
(8*4)+(7*7)+(6*7)+(5*2)+(4*4)+(3*8)+(2*7)+(1*1)=188
188 % 10 = 8
So 477248-71-8 is a valid CAS Registry Number.
