1109115-11-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1109115-11-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,9,1,1 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1109115-11:
(9*1)+(8*1)+(7*0)+(6*9)+(5*1)+(4*1)+(3*5)+(2*1)+(1*1)=98
98 % 10 = 8
So 1109115-11-8 is a valid CAS Registry Number.
