241155-45-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 241155-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,1,1,5 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 241155-45:
(8*2)+(7*4)+(6*1)+(5*1)+(4*5)+(3*5)+(2*4)+(1*5)=103
103 % 10 = 3
So 241155-45-3 is a valid CAS Registry Number.
