Check Digit Verification of cas no

The CAS Registry Mumber 28687-99-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,8 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 28687-99:
(7*2)+(6*8)+(5*6)+(4*8)+(3*7)+(2*9)+(1*9)=172
172 % 10 = 2
So 28687-99-2 is a valid CAS Registry Number.
