Check Digit Verification of cas no
The CAS Registry Mumber 204700-24-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,7,0 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 204700-24:
(8*2)+(7*0)+(6*4)+(5*7)+(4*0)+(3*0)+(2*2)+(1*4)=83
83 % 10 = 3
So 204700-24-3 is a valid CAS Registry Number.
