Check Digit Verification of cas no

The CAS Registry Mumber 293751-66-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,3,7,5 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 293751-66:
(8*2)+(7*9)+(6*3)+(5*7)+(4*5)+(3*1)+(2*6)+(1*6)=173
173 % 10 = 3
So 293751-66-3 is a valid CAS Registry Number.
