144490-25-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144490-25-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,9 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 144490-25:
(8*1)+(7*4)+(6*4)+(5*4)+(4*9)+(3*0)+(2*2)+(1*5)=125
125 % 10 = 5
So 144490-25-5 is a valid CAS Registry Number.
