141944-15-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141944-15-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,9,4 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 141944-15:
(8*1)+(7*4)+(6*1)+(5*9)+(4*4)+(3*4)+(2*1)+(1*5)=122
122 % 10 = 2
So 141944-15-2 is a valid CAS Registry Number.
