Check Digit Verification of cas no

The CAS Registry Mumber 20421-02-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,2 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20421-02:
(7*2)+(6*0)+(5*4)+(4*2)+(3*1)+(2*0)+(1*2)=47
47 % 10 = 7
So 20421-02-7 is a valid CAS Registry Number.
