83221-43-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83221-43-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,2,2 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.Calculate Digit Verification of CAS Registry Number 83221-43:
(7*8)+(6*3)+(5*2)+(4*2)+(3*1)+(2*4)+(1*3)=106
106 % 10 = 6
So 83221-43-6 is a valid CAS Registry Number.
