1044-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1044-89-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,4 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1044-89:
(6*1)+(5*0)+(4*4)+(3*4)+(2*8)+(1*9)=59
59 % 10 = 9
So 1044-89-9 is a valid CAS Registry Number.
