Check Digit Verification of cas no

The CAS Registry Mumber 213818-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,8,1 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 213818-72:
(8*2)+(7*1)+(6*3)+(5*8)+(4*1)+(3*8)+(2*7)+(1*2)=125
125 % 10 = 5
So 213818-72-5 is a valid CAS Registry Number.
