75153-42-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75153-42-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,1,5 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75153-42:
(7*7)+(6*5)+(5*1)+(4*5)+(3*3)+(2*4)+(1*2)=123
123 % 10 = 3
So 75153-42-3 is a valid CAS Registry Number.
