Check Digit Verification of cas no

The CAS Registry Mumber 128829-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,2 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128829-40:
(8*1)+(7*2)+(6*8)+(5*8)+(4*2)+(3*9)+(2*4)+(1*0)=153
153 % 10 = 3
So 128829-40-3 is a valid CAS Registry Number.
