Check Digit Verification of cas no

The CAS Registry Mumber 439912-48-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,9,1 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 439912-48:
(8*4)+(7*3)+(6*9)+(5*9)+(4*1)+(3*2)+(2*4)+(1*8)=178
178 % 10 = 8
So 439912-48-8 is a valid CAS Registry Number.
