Check Digit Verification of cas no
The CAS Registry Mumber 21944-44-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,4 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.Calculate Digit Verification of CAS Registry Number 21944-44:
(7*2)+(6*1)+(5*9)+(4*4)+(3*4)+(2*4)+(1*4)=105
105 % 10 = 5
So 21944-44-5 is a valid CAS Registry Number.
