Check Digit Verification of cas no

The CAS Registry Mumber 570-67-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,7 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 570-67:
(5*5)+(4*7)+(3*0)+(2*6)+(1*7)=72
72 % 10 = 2
So 570-67-2 is a valid CAS Registry Number.
