Check Digit Verification of cas no

The CAS Registry Mumber 549509-40-2 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 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 549509-40:
(8*5)+(7*4)+(6*9)+(5*5)+(4*0)+(3*9)+(2*4)+(1*0)=182
182 % 10 = 2
So 549509-40-2 is a valid CAS Registry Number.
