Check Digit Verification of cas no
The CAS Registry Mumber 189944-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,9,4 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 189944-74:
(8*1)+(7*8)+(6*9)+(5*9)+(4*4)+(3*4)+(2*7)+(1*4)=209
209 % 10 = 9
So 189944-74-9 is a valid CAS Registry Number.
