81528-11-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81528-11-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,2 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81528-11:
(7*8)+(6*1)+(5*5)+(4*2)+(3*8)+(2*1)+(1*1)=122
122 % 10 = 2
So 81528-11-2 is a valid CAS Registry Number.
