111109-11-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111109-11-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,1,0 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 111109-11:
(8*1)+(7*1)+(6*1)+(5*1)+(4*0)+(3*9)+(2*1)+(1*1)=56
56 % 10 = 6
So 111109-11-6 is a valid CAS Registry Number.
