75858-47-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75858-47-8 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, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75858-47:
(7*7)+(6*5)+(5*8)+(4*5)+(3*8)+(2*4)+(1*7)=178
178 % 10 = 8
So 75858-47-8 is a valid CAS Registry Number.
