75975-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75975-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,7 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75975-40:
(7*7)+(6*5)+(5*9)+(4*7)+(3*5)+(2*4)+(1*0)=175
175 % 10 = 5
So 75975-40-5 is a valid CAS Registry Number.
