Check Digit Verification of cas no

The CAS Registry Mumber 290-16-4 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 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 290-16:
(5*2)+(4*9)+(3*0)+(2*1)+(1*6)=54
54 % 10 = 4
So 290-16-4 is a valid CAS Registry Number.
