53963-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53963-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,9,6 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 53963-20:
(7*5)+(6*3)+(5*9)+(4*6)+(3*3)+(2*2)+(1*0)=135
135 % 10 = 5
So 53963-20-5 is a valid CAS Registry Number.
