84181-47-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84181-47-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,1,8 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84181-47:
(7*8)+(6*4)+(5*1)+(4*8)+(3*1)+(2*4)+(1*7)=135
135 % 10 = 5
So 84181-47-5 is a valid CAS Registry Number.
