Check Digit Verification of cas no

The CAS Registry Mumber 128143-56-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,1,4 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128143-56:
(8*1)+(7*2)+(6*8)+(5*1)+(4*4)+(3*3)+(2*5)+(1*6)=116
116 % 10 = 6
So 128143-56-6 is a valid CAS Registry Number.
