200061-43-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 200061-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,0,6 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 200061-43:
(8*2)+(7*0)+(6*0)+(5*0)+(4*6)+(3*1)+(2*4)+(1*3)=54
54 % 10 = 4
So 200061-43-4 is a valid CAS Registry Number.
