Check Digit Verification of cas no

The CAS Registry Mumber 123167-28-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,1,6 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 123167-28:
(8*1)+(7*2)+(6*3)+(5*1)+(4*6)+(3*7)+(2*2)+(1*8)=102
102 % 10 = 2
So 123167-28-2 is a valid CAS Registry Number.
