Check Digit Verification of cas no

The CAS Registry Mumber 91111-69-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,1 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91111-69:
(7*9)+(6*1)+(5*1)+(4*1)+(3*1)+(2*6)+(1*9)=102
102 % 10 = 2
So 91111-69-2 is a valid CAS Registry Number.
