Check Digit Verification of cas no

The CAS Registry Mumber 291752-73-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,1,7,5 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 291752-73:
(8*2)+(7*9)+(6*1)+(5*7)+(4*5)+(3*2)+(2*7)+(1*3)=163
163 % 10 = 3
So 291752-73-3 is a valid CAS Registry Number.
