Check Digit Verification of cas no

The CAS Registry Mumber 28831-89-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,8,3 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 28831-89:
(7*2)+(6*8)+(5*8)+(4*3)+(3*1)+(2*8)+(1*9)=142
142 % 10 = 2
So 28831-89-2 is a valid CAS Registry Number.
