19944-63-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19944-63-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,4 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 19944-63:
(7*1)+(6*9)+(5*9)+(4*4)+(3*4)+(2*6)+(1*3)=149
149 % 10 = 9
So 19944-63-9 is a valid CAS Registry Number.
