Check Digit Verification of cas no

The CAS Registry Mumber 501-91-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 501-91:
(5*5)+(4*0)+(3*1)+(2*9)+(1*1)=47
47 % 10 = 7
So 501-91-7 is a valid CAS Registry Number.
