80397-99-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80397-99-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,9 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 80397-99:
(7*8)+(6*0)+(5*3)+(4*9)+(3*7)+(2*9)+(1*9)=155
155 % 10 = 5
So 80397-99-5 is a valid CAS Registry Number.
