83541-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83541-80-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,4 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83541-80:
(7*8)+(6*3)+(5*5)+(4*4)+(3*1)+(2*8)+(1*0)=134
134 % 10 = 4
So 83541-80-4 is a valid CAS Registry Number.
