80541-11-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80541-11-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,4 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 80541-11:
(7*8)+(6*0)+(5*5)+(4*4)+(3*1)+(2*1)+(1*1)=103
103 % 10 = 3
So 80541-11-3 is a valid CAS Registry Number.
