Check Digit Verification of cas no

The CAS Registry Mumber 97689-87-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,6,8 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 97689-87:
(7*9)+(6*7)+(5*6)+(4*8)+(3*9)+(2*8)+(1*7)=217
217 % 10 = 7
So 97689-87-7 is a valid CAS Registry Number.
