84509-68-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84509-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,5,0 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 84509-68:
(7*8)+(6*4)+(5*5)+(4*0)+(3*9)+(2*6)+(1*8)=152
152 % 10 = 2
So 84509-68-2 is a valid CAS Registry Number.
