Check Digit Verification of cas no
The CAS Registry Mumber 140160-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,6 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 140160-91:
(8*1)+(7*4)+(6*0)+(5*1)+(4*6)+(3*0)+(2*9)+(1*1)=84
84 % 10 = 4
So 140160-91-4 is a valid CAS Registry Number.
