Check Digit Verification of cas no
The CAS Registry Mumber 240121-53-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,0,1,2 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 240121-53:
(8*2)+(7*4)+(6*0)+(5*1)+(4*2)+(3*1)+(2*5)+(1*3)=73
73 % 10 = 3
So 240121-53-3 is a valid CAS Registry Number.
