Check Digit Verification of cas no

The CAS Registry Mumber 869811-41-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,8,1 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 869811-41:
(8*8)+(7*6)+(6*9)+(5*8)+(4*1)+(3*1)+(2*4)+(1*1)=216
216 % 10 = 6
So 869811-41-6 is a valid CAS Registry Number.
