28561-52-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28561-52-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,5,6 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 28561-52:
(7*2)+(6*8)+(5*5)+(4*6)+(3*1)+(2*5)+(1*2)=126
126 % 10 = 6
So 28561-52-6 is a valid CAS Registry Number.
