Check Digit Verification of cas no

The CAS Registry Mumber 6919-81-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,1 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6919-81:
(6*6)+(5*9)+(4*1)+(3*9)+(2*8)+(1*1)=129
129 % 10 = 9
So 6919-81-9 is a valid CAS Registry Number.
