Check Digit Verification of cas no

The CAS Registry Mumber 1911-81-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,1 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1911-81:
(6*1)+(5*9)+(4*1)+(3*1)+(2*8)+(1*1)=75
75 % 10 = 5
So 1911-81-5 is a valid CAS Registry Number.
