55580-86-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55580-86-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,8 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 55580-86:
(7*5)+(6*5)+(5*5)+(4*8)+(3*0)+(2*8)+(1*6)=144
144 % 10 = 4
So 55580-86-4 is a valid CAS Registry Number.
