Check Digit Verification of cas no
The CAS Registry Mumber 144459-20-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,5 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144459-20:
(8*1)+(7*4)+(6*4)+(5*4)+(4*5)+(3*9)+(2*2)+(1*0)=131
131 % 10 = 1
So 144459-20-1 is a valid CAS Registry Number.
