Check Digit Verification of cas no

The CAS Registry Mumber 521981-98-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,1,9,8 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 521981-98:
(8*5)+(7*2)+(6*1)+(5*9)+(4*8)+(3*1)+(2*9)+(1*8)=166
166 % 10 = 6
So 521981-98-6 is a valid CAS Registry Number.
