Check Digit Verification of cas no
The CAS Registry Mumber 112889-02-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,8,8 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 112889-02:
(8*1)+(7*1)+(6*2)+(5*8)+(4*8)+(3*9)+(2*0)+(1*2)=128
128 % 10 = 8
So 112889-02-8 is a valid CAS Registry Number.
