Check Digit Verification of cas no

The CAS Registry Mumber 549501-26-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,9,5,0 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 549501-26:
(8*5)+(7*4)+(6*9)+(5*5)+(4*0)+(3*1)+(2*2)+(1*6)=160
160 % 10 = 0
So 549501-26-0 is a valid CAS Registry Number.
