444809-28-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 444809-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,8,0 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 444809-28:
(8*4)+(7*4)+(6*4)+(5*8)+(4*0)+(3*9)+(2*2)+(1*8)=163
163 % 10 = 3
So 444809-28-3 is a valid CAS Registry Number.
