Check Digit Verification of cas no

The CAS Registry Mumber 2161-22-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,6 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2161-22:
(6*2)+(5*1)+(4*6)+(3*1)+(2*2)+(1*2)=50
50 % 10 = 0
So 2161-22-0 is a valid CAS Registry Number.
