Check Digit Verification of cas no
The CAS Registry Mumber 116589-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,5,8 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 116589-23:
(8*1)+(7*1)+(6*6)+(5*5)+(4*8)+(3*9)+(2*2)+(1*3)=142
142 % 10 = 2
So 116589-23-2 is a valid CAS Registry Number.
