Check Digit Verification of cas no

The CAS Registry Mumber 13820-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,2 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13820-22:
(7*1)+(6*3)+(5*8)+(4*2)+(3*0)+(2*2)+(1*2)=79
79 % 10 = 9
So 13820-22-9 is a valid CAS Registry Number.
