Check Digit Verification of cas no

The CAS Registry Mumber 139220-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,2 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139220-72:
(8*1)+(7*3)+(6*9)+(5*2)+(4*2)+(3*0)+(2*7)+(1*2)=117
117 % 10 = 7
So 139220-72-7 is a valid CAS Registry Number.
