Check Digit Verification of cas no

The CAS Registry Mumber 74840-76-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,4 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74840-76:
(7*7)+(6*4)+(5*8)+(4*4)+(3*0)+(2*7)+(1*6)=149
149 % 10 = 9
So 74840-76-9 is a valid CAS Registry Number.
