Check Digit Verification of cas no

The CAS Registry Mumber 2473-16-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,7 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2473-16:
(6*2)+(5*4)+(4*7)+(3*3)+(2*1)+(1*6)=77
77 % 10 = 7
So 2473-16-7 is a valid CAS Registry Number.
