Check Digit Verification of cas no

The CAS Registry Mumber 66777-98-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,7,7 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 66777-98:
(7*6)+(6*6)+(5*7)+(4*7)+(3*7)+(2*9)+(1*8)=188
188 % 10 = 8
So 66777-98-8 is a valid CAS Registry Number.
