Check Digit Verification of cas no

The CAS Registry Mumber 40328-50-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,2 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40328-50:
(7*4)+(6*0)+(5*3)+(4*2)+(3*8)+(2*5)+(1*0)=85
85 % 10 = 5
So 40328-50-5 is a valid CAS Registry Number.
