Check Digit Verification of cas no

The CAS Registry Mumber 138942-82-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,4 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138942-82:
(8*1)+(7*3)+(6*8)+(5*9)+(4*4)+(3*2)+(2*8)+(1*2)=162
162 % 10 = 2
So 138942-82-2 is a valid CAS Registry Number.
