Check Digit Verification of cas no

The CAS Registry Mumber 80490-50-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,9 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 80490-50:
(7*8)+(6*0)+(5*4)+(4*9)+(3*0)+(2*5)+(1*0)=122
122 % 10 = 2
So 80490-50-2 is a valid CAS Registry Number.
