Check Digit Verification of cas no
The CAS Registry Mumber 128184-04-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,1,8 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128184-04:
(8*1)+(7*2)+(6*8)+(5*1)+(4*8)+(3*4)+(2*0)+(1*4)=123
123 % 10 = 3
So 128184-04-3 is a valid CAS Registry Number.
