75243-99-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75243-99-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,4 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 75243-99:
(7*7)+(6*5)+(5*2)+(4*4)+(3*3)+(2*9)+(1*9)=141
141 % 10 = 1
So 75243-99-1 is a valid CAS Registry Number.
