Check Digit Verification of cas no
The CAS Registry Mumber 119998-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,9 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119998-71:
(8*1)+(7*1)+(6*9)+(5*9)+(4*9)+(3*8)+(2*7)+(1*1)=189
189 % 10 = 9
So 119998-71-9 is a valid CAS Registry Number.
