Check Digit Verification of cas no

The CAS Registry Mumber 4181-31-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,8 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4181-31:
(6*4)+(5*1)+(4*8)+(3*1)+(2*3)+(1*1)=71
71 % 10 = 1
So 4181-31-1 is a valid CAS Registry Number.
