Check Digit Verification of cas no

The CAS Registry Mumber 81389-54-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,8 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81389-54:
(7*8)+(6*1)+(5*3)+(4*8)+(3*9)+(2*5)+(1*4)=150
150 % 10 = 0
So 81389-54-0 is a valid CAS Registry Number.
