Check Digit Verification of cas no

The CAS Registry Mumber 126228-87-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,2,2 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 126228-87:
(8*1)+(7*2)+(6*6)+(5*2)+(4*2)+(3*8)+(2*8)+(1*7)=123
123 % 10 = 3
So 126228-87-3 is a valid CAS Registry Number.
