75745-04-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75745-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,7,4 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 75745-04:
(7*7)+(6*5)+(5*7)+(4*4)+(3*5)+(2*0)+(1*4)=149
149 % 10 = 9
So 75745-04-9 is a valid CAS Registry Number.
