Check Digit Verification of cas no

The CAS Registry Mumber 903523-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,3,5,2 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 903523-85:
(8*9)+(7*0)+(6*3)+(5*5)+(4*2)+(3*3)+(2*8)+(1*5)=153
153 % 10 = 3
So 903523-85-3 is a valid CAS Registry Number.
