Check Digit Verification of cas no
The CAS Registry Mumber 71091-93-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,9 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 71091-93:
(7*7)+(6*1)+(5*0)+(4*9)+(3*1)+(2*9)+(1*3)=115
115 % 10 = 5
So 71091-93-5 is a valid CAS Registry Number.
