54352-47-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54352-47-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,3,5 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 54352-47:
(7*5)+(6*4)+(5*3)+(4*5)+(3*2)+(2*4)+(1*7)=115
115 % 10 = 5
So 54352-47-5 is a valid CAS Registry Number.
