Check Digit Verification of cas no

The CAS Registry Mumber 168412-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,4,1 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 168412-89:
(8*1)+(7*6)+(6*8)+(5*4)+(4*1)+(3*2)+(2*8)+(1*9)=153
153 % 10 = 3
So 168412-89-3 is a valid CAS Registry Number.
