Check Digit Verification of cas no

The CAS Registry Mumber 91284-80-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,2,8 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91284-80:
(7*9)+(6*1)+(5*2)+(4*8)+(3*4)+(2*8)+(1*0)=139
139 % 10 = 9
So 91284-80-9 is a valid CAS Registry Number.
