Check Digit Verification of cas no

The CAS Registry Mumber 59046-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,0,4 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 59046-50:
(7*5)+(6*9)+(5*0)+(4*4)+(3*6)+(2*5)+(1*0)=133
133 % 10 = 3
So 59046-50-3 is a valid CAS Registry Number.
