Check Digit Verification of cas no

The CAS Registry Mumber 144945-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,9,4 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144945-33:
(8*1)+(7*4)+(6*4)+(5*9)+(4*4)+(3*5)+(2*3)+(1*3)=145
145 % 10 = 5
So 144945-33-5 is a valid CAS Registry Number.
