107450-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107450-53-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,4,5 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 107450-53:
(8*1)+(7*0)+(6*7)+(5*4)+(4*5)+(3*0)+(2*5)+(1*3)=103
103 % 10 = 3
So 107450-53-3 is a valid CAS Registry Number.
