66472-53-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66472-53-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,7 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 66472-53:
(7*6)+(6*6)+(5*4)+(4*7)+(3*2)+(2*5)+(1*3)=145
145 % 10 = 5
So 66472-53-5 is a valid CAS Registry Number.
