Check Digit Verification of cas no
The CAS Registry Mumber 434343-06-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,4,3,4 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 434343-06:
(8*4)+(7*3)+(6*4)+(5*3)+(4*4)+(3*3)+(2*0)+(1*6)=123
123 % 10 = 3
So 434343-06-3 is a valid CAS Registry Number.
