Check Digit Verification of cas no

The CAS Registry Mumber 18954-66-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,5 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 18954-66:
(7*1)+(6*8)+(5*9)+(4*5)+(3*4)+(2*6)+(1*6)=150
150 % 10 = 0
So 18954-66-0 is a valid CAS Registry Number.
