75858-35-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75858-35-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,8,5 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 75858-35:
(7*7)+(6*5)+(5*8)+(4*5)+(3*8)+(2*3)+(1*5)=174
174 % 10 = 4
So 75858-35-4 is a valid CAS Registry Number.
