244169-09-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 244169-09-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,1,6 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 244169-09:
(8*2)+(7*4)+(6*4)+(5*1)+(4*6)+(3*9)+(2*0)+(1*9)=133
133 % 10 = 3
So 244169-09-3 is a valid CAS Registry Number.
