745033-24-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 745033-24-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,5,0,3 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 745033-24:
(8*7)+(7*4)+(6*5)+(5*0)+(4*3)+(3*3)+(2*2)+(1*4)=143
143 % 10 = 3
So 745033-24-3 is a valid CAS Registry Number.
