Check Digit Verification of cas no

The CAS Registry Mumber 126525-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,2 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 126525-87:
(8*1)+(7*2)+(6*6)+(5*5)+(4*2)+(3*5)+(2*8)+(1*7)=129
129 % 10 = 9
So 126525-87-9 is a valid CAS Registry Number.
