Check Digit Verification of cas no

The CAS Registry Mumber 4427-20-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,2 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4427-20:
(6*4)+(5*4)+(4*2)+(3*7)+(2*2)+(1*0)=77
77 % 10 = 7
So 4427-20-7 is a valid CAS Registry Number.
