81280-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81280-91-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,8 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81280-91:
(7*8)+(6*1)+(5*2)+(4*8)+(3*0)+(2*9)+(1*1)=123
123 % 10 = 3
So 81280-91-3 is a valid CAS Registry Number.
