Check Digit Verification of cas no

The CAS Registry Mumber 65939-87-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,9,3 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 65939-87:
(7*6)+(6*5)+(5*9)+(4*3)+(3*9)+(2*8)+(1*7)=179
179 % 10 = 9
So 65939-87-9 is a valid CAS Registry Number.
