Check Digit Verification of cas no

The CAS Registry Mumber 73009-76-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,0,0 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 73009-76:
(7*7)+(6*3)+(5*0)+(4*0)+(3*9)+(2*7)+(1*6)=114
114 % 10 = 4
So 73009-76-4 is a valid CAS Registry Number.
