Check Digit Verification of cas no
The CAS Registry Mumber 81995-11-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,9 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81995-11:
(7*8)+(6*1)+(5*9)+(4*9)+(3*5)+(2*1)+(1*1)=161
161 % 10 = 1
So 81995-11-1 is a valid CAS Registry Number.
