545444-98-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 545444-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,5,4,4 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 545444-98:
(8*5)+(7*4)+(6*5)+(5*4)+(4*4)+(3*4)+(2*9)+(1*8)=172
172 % 10 = 2
So 545444-98-2 is a valid CAS Registry Number.
