75318-40-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75318-40-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,3,1 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75318-40:
(7*7)+(6*5)+(5*3)+(4*1)+(3*8)+(2*4)+(1*0)=130
130 % 10 = 0
So 75318-40-0 is a valid CAS Registry Number.
