Check Digit Verification of cas no

The CAS Registry Mumber 70020-14-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,0,2 and 0 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 70020-14:
(7*7)+(6*0)+(5*0)+(4*2)+(3*0)+(2*1)+(1*4)=63
63 % 10 = 3
So 70020-14-3 is a valid CAS Registry Number.
