75424-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75424-50-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,2 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75424-50:
(7*7)+(6*5)+(5*4)+(4*2)+(3*4)+(2*5)+(1*0)=129
129 % 10 = 9
So 75424-50-9 is a valid CAS Registry Number.
