Check Digit Verification of cas no

The CAS Registry Mumber 959511-66-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,9,5,1 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 959511-66:
(8*9)+(7*5)+(6*9)+(5*5)+(4*1)+(3*1)+(2*6)+(1*6)=211
211 % 10 = 1
So 959511-66-1 is a valid CAS Registry Number.
