Check Digit Verification of cas no

The CAS Registry Mumber 190438-01-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,4,3 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 190438-01:
(8*1)+(7*9)+(6*0)+(5*4)+(4*3)+(3*8)+(2*0)+(1*1)=128
128 % 10 = 8
So 190438-01-8 is a valid CAS Registry Number.
