84081-68-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84081-68-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,0,8 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 84081-68:
(7*8)+(6*4)+(5*0)+(4*8)+(3*1)+(2*6)+(1*8)=135
135 % 10 = 5
So 84081-68-5 is a valid CAS Registry Number.
