75509-74-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75509-74-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,0 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 75509-74:
(7*7)+(6*5)+(5*5)+(4*0)+(3*9)+(2*7)+(1*4)=149
149 % 10 = 9
So 75509-74-9 is a valid CAS Registry Number.
