Check Digit Verification of cas no

The CAS Registry Mumber 96644-14-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,6,4 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 96644-14:
(7*9)+(6*6)+(5*6)+(4*4)+(3*4)+(2*1)+(1*4)=163
163 % 10 = 3
So 96644-14-3 is a valid CAS Registry Number.
