4-5Check Digit Verification of cas no
The CAS Registry Mumber 82944-44-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,4 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.Calculate Digit Verification of CAS Registry Number 82944-44:
(7*8)+(6*2)+(5*9)+(4*4)+(3*4)+(2*4)+(1*4)=153
153 % 10 = 3
So 82944-44-3 is a valid CAS Registry Number.
