1144044-97-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1144044-97-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,4,0,4 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1144044-97:
(9*1)+(8*1)+(7*4)+(6*4)+(5*0)+(4*4)+(3*4)+(2*9)+(1*7)=122
122 % 10 = 2
So 1144044-97-2 is a valid CAS Registry Number.
