55449-84-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55449-84-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,4,4 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 55449-84:
(7*5)+(6*5)+(5*4)+(4*4)+(3*9)+(2*8)+(1*4)=148
148 % 10 = 8
So 55449-84-8 is a valid CAS Registry Number.
