Check Digit Verification of cas no

The CAS Registry Mumber 18822-51-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,2 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18822-51:
(7*1)+(6*8)+(5*8)+(4*2)+(3*2)+(2*5)+(1*1)=120
120 % 10 = 0
So 18822-51-0 is a valid CAS Registry Number.
