127944-05-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127944-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,4 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 127944-05:
(8*1)+(7*2)+(6*7)+(5*9)+(4*4)+(3*4)+(2*0)+(1*5)=142
142 % 10 = 2
So 127944-05-2 is a valid CAS Registry Number.
