109533-19-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109533-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,5,3 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109533-19:
(8*1)+(7*0)+(6*9)+(5*5)+(4*3)+(3*3)+(2*1)+(1*9)=119
119 % 10 = 9
So 109533-19-9 is a valid CAS Registry Number.
