84541-83-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84541-83-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,5,4 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 84541-83:
(7*8)+(6*4)+(5*5)+(4*4)+(3*1)+(2*8)+(1*3)=143
143 % 10 = 3
So 84541-83-3 is a valid CAS Registry Number.
