Check Digit Verification of cas no

The CAS Registry Mumber 509-92-2 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 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 509-92:
(5*5)+(4*0)+(3*9)+(2*9)+(1*2)=72
72 % 10 = 2
So 509-92-2 is a valid CAS Registry Number.
