52210-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52210-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,2,1 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 52210-20:
(7*5)+(6*2)+(5*2)+(4*1)+(3*0)+(2*2)+(1*0)=65
65 % 10 = 5
So 52210-20-5 is a valid CAS Registry Number.
