Check Digit Verification of cas no

The CAS Registry Mumber 128949-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,4 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128949-20:
(8*1)+(7*2)+(6*8)+(5*9)+(4*4)+(3*9)+(2*2)+(1*0)=162
162 % 10 = 2
So 128949-20-2 is a valid CAS Registry Number.
