77944-04-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77944-04-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,4 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77944-04:
(7*7)+(6*7)+(5*9)+(4*4)+(3*4)+(2*0)+(1*4)=168
168 % 10 = 8
So 77944-04-8 is a valid CAS Registry Number.
