Check Digit Verification of cas no

The CAS Registry Mumber 3081-20-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,8 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3081-20:
(6*3)+(5*0)+(4*8)+(3*1)+(2*2)+(1*0)=57
57 % 10 = 7
So 3081-20-7 is a valid CAS Registry Number.
