4488-19-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4488-19-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,8 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4488-19:
(6*4)+(5*4)+(4*8)+(3*8)+(2*1)+(1*9)=111
111 % 10 = 1
So 4488-19-1 is a valid CAS Registry Number.
