55343-20-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55343-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,3,4 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 55343-20:
(7*5)+(6*5)+(5*3)+(4*4)+(3*3)+(2*2)+(1*0)=109
109 % 10 = 9
So 55343-20-9 is a valid CAS Registry Number.
