Check Digit Verification of cas no

The CAS Registry Mumber 246871-23-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,6,8,7 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 246871-23:
(8*2)+(7*4)+(6*6)+(5*8)+(4*7)+(3*1)+(2*2)+(1*3)=158
158 % 10 = 8
So 246871-23-8 is a valid CAS Registry Number.
