Check Digit Verification of cas no
The CAS Registry Mumber 143466-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,4,6 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 143466-45:
(8*1)+(7*4)+(6*3)+(5*4)+(4*6)+(3*6)+(2*4)+(1*5)=129
129 % 10 = 9
So 143466-45-9 is a valid CAS Registry Number.
