Check Digit Verification of cas no

The CAS Registry Mumber 72963-93-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,9,6 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 72963-93:
(7*7)+(6*2)+(5*9)+(4*6)+(3*3)+(2*9)+(1*3)=160
160 % 10 = 0
So 72963-93-0 is a valid CAS Registry Number.
