80675-57-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80675-57-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,7 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80675-57:
(7*8)+(6*0)+(5*6)+(4*7)+(3*5)+(2*5)+(1*7)=146
146 % 10 = 6
So 80675-57-6 is a valid CAS Registry Number.
