Check Digit Verification of cas no
The CAS Registry Mumber 450408-67-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,0,4,0 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 450408-67:
(8*4)+(7*5)+(6*0)+(5*4)+(4*0)+(3*8)+(2*6)+(1*7)=130
130 % 10 = 0
So 450408-67-0 is a valid CAS Registry Number.
