243980-05-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 243980-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,3,9,8 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 243980-05:
(8*2)+(7*4)+(6*3)+(5*9)+(4*8)+(3*0)+(2*0)+(1*5)=144
144 % 10 = 4
So 243980-05-4 is a valid CAS Registry Number.
