Check Digit Verification of cas no

The CAS Registry Mumber 541515-66-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,1,5,1 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 541515-66:
(8*5)+(7*4)+(6*1)+(5*5)+(4*1)+(3*5)+(2*6)+(1*6)=136
136 % 10 = 6
So 541515-66-6 is a valid CAS Registry Number.
