Check Digit Verification of cas no

The CAS Registry Mumber 4931-81-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,3 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4931-81:
(6*4)+(5*9)+(4*3)+(3*1)+(2*8)+(1*1)=101
101 % 10 = 1
So 4931-81-1 is a valid CAS Registry Number.
