Check Digit Verification of cas no

The CAS Registry Mumber 272459-41-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,2,4,5 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 272459-41:
(8*2)+(7*7)+(6*2)+(5*4)+(4*5)+(3*9)+(2*4)+(1*1)=153
153 % 10 = 3
So 272459-41-3 is a valid CAS Registry Number.
