Check Digit Verification of cas no

The CAS Registry Mumber 128683-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,8 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128683-74:
(8*1)+(7*2)+(6*8)+(5*6)+(4*8)+(3*3)+(2*7)+(1*4)=159
159 % 10 = 9
So 128683-74-9 is a valid CAS Registry Number.
