Check Digit Verification of cas no
The CAS Registry Mumber 141743-43-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,7,4 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 141743-43:
(8*1)+(7*4)+(6*1)+(5*7)+(4*4)+(3*3)+(2*4)+(1*3)=113
113 % 10 = 3
So 141743-43-3 is a valid CAS Registry Number.
