109267-14-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109267-14-3 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 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 109267-14:
(8*1)+(7*0)+(6*9)+(5*2)+(4*6)+(3*7)+(2*1)+(1*4)=123
123 % 10 = 3
So 109267-14-3 is a valid CAS Registry Number.
