Check Digit Verification of cas no

The CAS Registry Mumber 291-13-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,9 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 291-13:
(5*2)+(4*9)+(3*1)+(2*1)+(1*3)=54
54 % 10 = 4
So 291-13-4 is a valid CAS Registry Number.
