Check Digit Verification of cas no
The CAS Registry Mumber 81-05-0 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81-05:
(4*8)+(3*1)+(2*0)+(1*5)=40
40 % 10 = 0
So 81-05-0 is a valid CAS Registry Number.
