109263-16-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109263-16-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,2,6 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 109263-16:
(8*1)+(7*0)+(6*9)+(5*2)+(4*6)+(3*3)+(2*1)+(1*6)=113
113 % 10 = 3
So 109263-16-3 is a valid CAS Registry Number.
