Check Digit Verification of cas no
The CAS Registry Mumber 81411-78-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,1 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81411-78:
(7*8)+(6*1)+(5*4)+(4*1)+(3*1)+(2*7)+(1*8)=111
111 % 10 = 1
So 81411-78-1 is a valid CAS Registry Number.
