Check Digit Verification of cas no

The CAS Registry Mumber 139957-82-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,5 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139957-82:
(8*1)+(7*3)+(6*9)+(5*9)+(4*5)+(3*7)+(2*8)+(1*2)=187
187 % 10 = 7
So 139957-82-7 is a valid CAS Registry Number.
