Check Digit Verification of cas no

The CAS Registry Mumber 74711-29-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,1 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74711-29:
(7*7)+(6*4)+(5*7)+(4*1)+(3*1)+(2*2)+(1*9)=128
128 % 10 = 8
So 74711-29-8 is a valid CAS Registry Number.
