1109273-65-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1109273-65-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,9,2,7 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1109273-65:
(9*1)+(8*1)+(7*0)+(6*9)+(5*2)+(4*7)+(3*3)+(2*6)+(1*5)=135
135 % 10 = 5
So 1109273-65-5 is a valid CAS Registry Number.
