Check Digit Verification of cas no
The CAS Registry Mumber 113203-28-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,2,0 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 113203-28:
(8*1)+(7*1)+(6*3)+(5*2)+(4*0)+(3*3)+(2*2)+(1*8)=64
64 % 10 = 4
So 113203-28-4 is a valid CAS Registry Number.
