52028-33-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52028-33-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,0,2 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 52028-33:
(7*5)+(6*2)+(5*0)+(4*2)+(3*8)+(2*3)+(1*3)=88
88 % 10 = 8
So 52028-33-8 is a valid CAS Registry Number.
