Check Digit Verification of cas no

The CAS Registry Mumber 144658-16-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,5 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 144658-16:
(8*1)+(7*4)+(6*4)+(5*6)+(4*5)+(3*8)+(2*1)+(1*6)=142
142 % 10 = 2
So 144658-16-2 is a valid CAS Registry Number.
