75858-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75858-33-2 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 3 respectively.
Calculate Digit Verification of CAS Registry Number 75858-33:
(7*7)+(6*5)+(5*8)+(4*5)+(3*8)+(2*3)+(1*3)=172
172 % 10 = 2
So 75858-33-2 is a valid CAS Registry Number.
