Check Digit Verification of cas no

The CAS Registry Mumber 128038-44-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,3 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128038-44:
(8*1)+(7*2)+(6*8)+(5*0)+(4*3)+(3*8)+(2*4)+(1*4)=118
118 % 10 = 8
So 128038-44-8 is a valid CAS Registry Number.
