55980-84-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55980-84-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,9,8 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 55980-84:
(7*5)+(6*5)+(5*9)+(4*8)+(3*0)+(2*8)+(1*4)=162
162 % 10 = 2
So 55980-84-2 is a valid CAS Registry Number.
