Check Digit Verification of cas no

The CAS Registry Mumber 139732-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,7,3 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139732-03:
(8*1)+(7*3)+(6*9)+(5*7)+(4*3)+(3*2)+(2*0)+(1*3)=139
139 % 10 = 9
So 139732-03-9 is a valid CAS Registry Number.
