1199944-08-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1199944-08-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,9,9,4 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1199944-08:
(9*1)+(8*1)+(7*9)+(6*9)+(5*9)+(4*4)+(3*4)+(2*0)+(1*8)=215
215 % 10 = 5
So 1199944-08-5 is a valid CAS Registry Number.
