Check Digit Verification of cas no
The CAS Registry Mumber 19441-09-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,4 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 19441-09:
(7*1)+(6*9)+(5*4)+(4*4)+(3*1)+(2*0)+(1*9)=109
109 % 10 = 9
So 19441-09-9 is a valid CAS Registry Number.
