75233-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75233-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,3 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75233-17:
(7*7)+(6*5)+(5*2)+(4*3)+(3*3)+(2*1)+(1*7)=119
119 % 10 = 9
So 75233-17-9 is a valid CAS Registry Number.
