Check Digit Verification of cas no

The CAS Registry Mumber 144850-53-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,8,5 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144850-53:
(8*1)+(7*4)+(6*4)+(5*8)+(4*5)+(3*0)+(2*5)+(1*3)=133
133 % 10 = 3
So 144850-53-3 is a valid CAS Registry Number.
