Check Digit Verification of cas no

The CAS Registry Mumber 128405-07-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,0 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128405-07:
(8*1)+(7*2)+(6*8)+(5*4)+(4*0)+(3*5)+(2*0)+(1*7)=112
112 % 10 = 2
So 128405-07-2 is a valid CAS Registry Number.
