Check Digit Verification of cas no

The CAS Registry Mumber 286961-14-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,6,9,6 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 286961-14:
(8*2)+(7*8)+(6*6)+(5*9)+(4*6)+(3*1)+(2*1)+(1*4)=186
186 % 10 = 6
So 286961-14-6 is a valid CAS Registry Number.
