118468-43-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118468-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,4,6 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 118468-43:
(8*1)+(7*1)+(6*8)+(5*4)+(4*6)+(3*8)+(2*4)+(1*3)=142
142 % 10 = 2
So 118468-43-2 is a valid CAS Registry Number.
