1109232-80-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1109232-80-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,9,2,3 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1109232-80:
(9*1)+(8*1)+(7*0)+(6*9)+(5*2)+(4*3)+(3*2)+(2*8)+(1*0)=115
115 % 10 = 5
So 1109232-80-5 is a valid CAS Registry Number.
