Check Digit Verification of cas no

The CAS Registry Mumber 439859-82-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,8,5 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 439859-82:
(8*4)+(7*3)+(6*9)+(5*8)+(4*5)+(3*9)+(2*8)+(1*2)=212
212 % 10 = 2
So 439859-82-2 is a valid CAS Registry Number.
