Check Digit Verification of cas no

The CAS Registry Mumber 140870-46-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,7 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 140870-46:
(8*1)+(7*4)+(6*0)+(5*8)+(4*7)+(3*0)+(2*4)+(1*6)=118
118 % 10 = 8
So 140870-46-8 is a valid CAS Registry Number.
