Check Digit Verification of cas no

The CAS Registry Mumber 73949-67-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,9,4 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73949-67:
(7*7)+(6*3)+(5*9)+(4*4)+(3*9)+(2*6)+(1*7)=174
174 % 10 = 4
So 73949-67-4 is a valid CAS Registry Number.
