Check Digit Verification of cas no

The CAS Registry Mumber 91502-28-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,0 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91502-28:
(7*9)+(6*1)+(5*5)+(4*0)+(3*2)+(2*2)+(1*8)=112
112 % 10 = 2
So 91502-28-2 is a valid CAS Registry Number.
