Check Digit Verification of cas no

The CAS Registry Mumber 143868-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,6 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 143868-68:
(8*1)+(7*4)+(6*3)+(5*8)+(4*6)+(3*8)+(2*6)+(1*8)=162
162 % 10 = 2
So 143868-68-2 is a valid CAS Registry Number.
