Check Digit Verification of cas no

The CAS Registry Mumber 74966-44-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,6 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74966-44:
(7*7)+(6*4)+(5*9)+(4*6)+(3*6)+(2*4)+(1*4)=172
172 % 10 = 2
So 74966-44-2 is a valid CAS Registry Number.
