Check Digit Verification of cas no

The CAS Registry Mumber 879416-91-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,9,4,1 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 879416-91:
(8*8)+(7*7)+(6*9)+(5*4)+(4*1)+(3*6)+(2*9)+(1*1)=228
228 % 10 = 8
So 879416-91-8 is a valid CAS Registry Number.
