80597-51-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80597-51-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,9 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 80597-51:
(7*8)+(6*0)+(5*5)+(4*9)+(3*7)+(2*5)+(1*1)=149
149 % 10 = 9
So 80597-51-9 is a valid CAS Registry Number.
