80554-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80554-76-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,5 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 80554-76:
(7*8)+(6*0)+(5*5)+(4*5)+(3*4)+(2*7)+(1*6)=133
133 % 10 = 3
So 80554-76-3 is a valid CAS Registry Number.
