Check Digit Verification of cas no
The CAS Registry Mumber 140173-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,7 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 140173-19:
(8*1)+(7*4)+(6*0)+(5*1)+(4*7)+(3*3)+(2*1)+(1*9)=89
89 % 10 = 9
So 140173-19-9 is a valid CAS Registry Number.
