Check Digit Verification of cas no

The CAS Registry Mumber 143996-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,9,9 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143996-52:
(8*1)+(7*4)+(6*3)+(5*9)+(4*9)+(3*6)+(2*5)+(1*2)=165
165 % 10 = 5
So 143996-52-5 is a valid CAS Registry Number.
