Check Digit Verification of cas no

The CAS Registry Mumber 163688-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,6,8 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 163688-20:
(8*1)+(7*6)+(6*3)+(5*6)+(4*8)+(3*8)+(2*2)+(1*0)=158
158 % 10 = 8
So 163688-20-8 is a valid CAS Registry Number.
