Check Digit Verification of cas no

The CAS Registry Mumber 128788-36-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,8 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128788-36:
(8*1)+(7*2)+(6*8)+(5*7)+(4*8)+(3*8)+(2*3)+(1*6)=173
173 % 10 = 3
So 128788-36-3 is a valid CAS Registry Number.
