Check Digit Verification of cas no
The CAS Registry Mumber 81-06-1 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 6 respectively.
Calculate Digit Verification of CAS Registry Number 81-06:
(4*8)+(3*1)+(2*0)+(1*6)=41
41 % 10 = 1
So 81-06-1 is a valid CAS Registry Number.
