Check Digit Verification of cas no

The CAS Registry Mumber 903550-32-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,3,5,5 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 903550-32:
(8*9)+(7*0)+(6*3)+(5*5)+(4*5)+(3*0)+(2*3)+(1*2)=143
143 % 10 = 3
So 903550-32-3 is a valid CAS Registry Number.
