Check Digit Verification of cas no

The CAS Registry Mumber 7240-54-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,4 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7240-54:
(6*7)+(5*2)+(4*4)+(3*0)+(2*5)+(1*4)=82
82 % 10 = 2
So 7240-54-2 is a valid CAS Registry Number.
