Check Digit Verification of cas no

The CAS Registry Mumber 123289-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,2,8 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 123289-71:
(8*1)+(7*2)+(6*3)+(5*2)+(4*8)+(3*9)+(2*7)+(1*1)=124
124 % 10 = 4
So 123289-71-4 is a valid CAS Registry Number.
