1440968-41-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1440968-41-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,9,6 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1440968-41:
(9*1)+(8*4)+(7*4)+(6*0)+(5*9)+(4*6)+(3*8)+(2*4)+(1*1)=171
171 % 10 = 1
So 1440968-41-1 is a valid CAS Registry Number.
