82009-45-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82009-45-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,0,0 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 82009-45:
(7*8)+(6*2)+(5*0)+(4*0)+(3*9)+(2*4)+(1*5)=108
108 % 10 = 8
So 82009-45-8 is a valid CAS Registry Number.
