83443-06-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83443-06-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,4 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 83443-06:
(7*8)+(6*3)+(5*4)+(4*4)+(3*3)+(2*0)+(1*6)=125
125 % 10 = 5
So 83443-06-5 is a valid CAS Registry Number.
