Check Digit Verification of cas no

The CAS Registry Mumber 7297-54-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,9 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7297-54:
(6*7)+(5*2)+(4*9)+(3*7)+(2*5)+(1*4)=123
123 % 10 = 3
So 7297-54-3 is a valid CAS Registry Number.
